wttmrwolf Posted April 30, 2009 Share Posted April 30, 2009 (edited) Hi Folks, Picked up an old punt for $200 with 5HP and its a bit worse for wear. No major leaks but it looks haggard. I bought all the sanding gear (rotory disks, brushes) but it taking for ever to take off the old paint. Can I use paint stripper to dissolve off the old paint. I bought some citrus paint remover which does nothing except smell nice. I'm want to use the strong paint stripper but is it going to eat through the hull? Interested to hear others thoughts. Maybe a chemist is in the house. Ben Edited April 30, 2009 by wttmrwolf Link to comment Share on other sites More sharing options...
BlacknBlue Posted April 30, 2009 Share Posted April 30, 2009 (edited) you could just get it soda blasted, will come up like new, giving a clean canvas to work with I looked in the yellow pages and found this mob fairly quickly http://www.yellowpages.com.au/onlineSoluti...roductId=215516 ps I have no connection with this business Edited April 30, 2009 by BlacknBlue Link to comment Share on other sites More sharing options...
ant180 Posted May 3, 2009 Share Posted May 3, 2009 I have painted a couple of boats. I like a chemical stripper, then an orbital sander with 180 grit. You need to get all of the aluminium properly sanded then etch primed to get good adhesion. If you use the products available to the general public then it will peel. 2k catalysed urethanes are about all that will protect and keep a shine. Not worth it on a $200 punt. My punt has more money worth of paint on it than what it is worth, only because I had the paint laying around. Link to comment Share on other sites More sharing options...
wonniefisho Posted May 3, 2009 Share Posted May 3, 2009 The orange stuff works, but you need multiple fairly thick coats. And yes, you will spend $500 in stripper on a $200 boat. Link to comment Share on other sites More sharing options...
Seagoon Posted May 3, 2009 Share Posted May 3, 2009 (edited) I concur on the volume of stripper. I repainted my fella about 2yrs ago, and its not a small job, I can tell you. I went through many, many litres of stripper. And countless manhours of elbow grease. Seriously, get it blasted, as the BlacknBlue suggested. In hindsight, I would have. I know nothing about this process though. A have heard that sandblasting is no good for aluminum? The thing about the blasting is that may allow the paint to key (if it is anything like sandblasting). And this is a DOUBLE BONUS, because you don't need to etch the aluminum, probably. The process i went through: scrape strip wire brush clean fill sand etch prime paint Add to that the removal of all the fittings, and it becomes an effort. I'd suggest that fishing is more fun!! But I understand your motivation because I have done it myself. In hindsight, I'd probably not bother, or buy a new boat. But I am extremely happy with my boat and the result. PS BlacknBlue, are you a Chain fan? Edited May 3, 2009 by Seagoon Link to comment Share on other sites More sharing options...
wttmrwolf Posted May 4, 2009 Author Share Posted May 4, 2009 Thanks for all the advice peoples I agree the stripping is turning into a royal pain in the backside. I'm calling around to see if I can get it sandblasted and save some $$$ on stripper. Used over 1 L to strip a tiny section. I'll be starting a thread soon with some photos so you can all follow along for the ride. Thanks again for all the tips. This is more a pet project because I have an empty double garage and I don't sleep that much. Link to comment Share on other sites More sharing options...
Seagoon Posted May 4, 2009 Share Posted May 4, 2009 Hi mate, I understand - there is more to it than just the outcome. There is the process, and also the satisfaction etc etc. A man has to have a hobby! Also, you will know your boat inside out once you have done it. Looking forward to seeing the photos come along :-) Cheers, Jon Link to comment Share on other sites More sharing options...

Looking forward to seeing the photos come along :-) Cheers, Jon Hi jon, I'm interested in the process you went through on your boat. Did you use a car repair style bog to "fill" small dents? Not sure if I should try my hand at panel beating or filling. Did you find a good bog? Found a soda blasting shop nearby. Got a quote over the phone of about $400-$500. I think I'll use up the last 4L of stripper I have on the stubborn paint so when he quotes properly I can get it down below $300. Its going to be a few late nights this week with the gas mask on. Fun fun fun. Ben Link to comment Share on other sites More sharing options...
Seagoon Posted May 4, 2009 Share Posted May 4, 2009 Hi mate, Sounds like a plan, re the stripper then the soda blasting. I recommend buying a few of those $2 plastic drop sheets from a HW shop plus some tape, and wrapping up the boat in between blasting and the first coat of paint - just to keep it in tip top condition. A bit like this: http://fishraider.com.au/Invision/index.ph...st&p=148351 I'm not sure how the soda blasting compares to the sand blasting in terms of allowing the paint to key, so you may or may not have to etch the aluminium. The undercoat on my boat is on really well - it's there for good. I etched then under coated, within a day or so of each other. The top coats came a month later, so they haven't knitted so well to the undercoats. But the undercoat will not come off, even with bangs where the top coat has chipped off, the primer is on for good. So I'd recommend doing all the painting within the minimum time separation allowed. Are you going to spray it? If so consider 2 pack. I didn't, but it may make life easier because of the faster drying. Geoff, who is a regular on this site recommended selleys plastibond to me for filling the holes/dings/scratches/pitting, and I too can recommend it. Its excellent. It's an epoxy, so it dries fast, and eventually very hard. And you can sand it. It has a little bit of flex too, so its not brittle. I'd also recommend 3M blue masking tape. Cheap masking tape is rubbish and is a NIGHTMARE to get off. The blue stuff is good. Mate I could talk for hours about this - PM me if you have any questions - also I know from first hand experience that this site is loaded with very helpful and knowledgable people. And very generous too. A few links to my boat stuff: http://fishraider.com.au/Invision/index.ph...st&p=164964 http://fishraider.com.au/Invision/index.ph...st&p=164967 http://fishraider.com.au/Invision/index.ph...st&p=144776 http://fishraider.com.au/Invision/index.ph...st&p=148706 http://fishraider.com.au/Invision/index.ph...st&p=148351 Cheers, Jon Link to comment Share on other sites More sharing options...
wttmrwolf Posted May 5, 2009 Author Share Posted May 5, 2009 Thanks Jon, That restoration you did on your boat gives me hope. I'm at the early stages where I'm still full of energy and scraping away paint using stipper. I was up until 2am last night. The neighbour popped his head out the window to see what all the racket was, woops. Now I've just spent all morning at work reading all your posts. I'm using up the last tin of stripper then taking it for a soda blasting quote. I figure if I remove all the stubborn paint when they quote it will be a bit cheaper. I've removed 90% of the paint from the inside. Yay! I loved the idea you had to wrap in plastic after blasting. Would be a shame to get any grime or corrosion before painting. Luckily I have a spray gun. Need to build a spray booth in my garage with plastic sheeting. I don't think the kids will like the smell of 2 pac paint wofting up into their bedrooms (or the ) Wait until people see how old this punt is. They will think I've gone completely insane. It fills time while I wait for the right conditions for Jew fishing. Later this week should be good. thursday or friday I'm taking a break from boat repairs to catch some fish.

Seagoon Posted May 5, 2009 Share Posted May 5, 2009 Mate - that's the key - go hard while the motivation is high! Putting all the fittings back on is the fun part, especially when you have some new fittings or ideas to try. It's a bit like decorating a cake that you have spent ages making - that said I have no idea what decorating a cake is like....! Link to comment Share on other sites More sharing options...
kingie chaser Posted September 22, 2016 Share Posted September 22, 2016 Reviving this old thread as I am about to do the same thing. My question is,- is it absolutely necessary to take %100 of the old paint off if you are going to paint it the same colour?? Link to comment Share on other sites More sharing options...
tryhard Posted September 22, 2016 Share Posted September 22, 2016 if you don't remove all the old paint, you will fin that it will "bloom" when you apply the new etch prime. in other words, remove all the paint! good luck Link to comment Share on other sites More sharing options...
Fab1 Posted September 22, 2016 Share Posted September 22, 2016 if you don't remove all the old paint, you will fin that it will "bloom" when you apply the new etch prime. in other words, remove all the paint! good luck Blooming is "normally" caused by moisture trapped between the paint layers and spraying when it's too cold or high humidity identified by a milkish appearance to the surface of the top coat.The cure is having a well prepared clean surface,using filtered air and heat lamps if spraying in cold conditions. What your referring to I think is "Frying" which is caused by many things including not feathering your paint edges properly or spraying over incompatible paint.Again the cure is prep-work,cleanliness and sealing the old surface before applying the new paint. By the way it's totally illegal to spray paint 2k paint outside an approved spray booth. Hope this clears a few things up. Link to comment Share on other sites More sharing options...
antonywardle Posted September 23, 2016 Share Posted September 23, 2016 Can you use a heat gun and a scraper to remove the paint? What does Al melt at? Link to comment Share on other sites More sharing options...
