adkel53 Posted January 23, 2011 Share Posted January 23, 2011 My trailer has a significant amount of surface rust on the axle. The rest is in good order. My thoughts are to remove the surface rust with a wire brush attached to a drill, treat with rust converter and the apply fishoil. I could possibly paint it with cold gal before the fishoil. Any thoughts from other Raiders? cheers Kel Link to comment Share on other sites More sharing options...
Yarraone Posted January 23, 2011 Share Posted January 23, 2011 I wouldnt worry to much about the cold gal..Prepare the surface as yu have said ..paint with a primmer/kill rust, allow to dry and set as per directions..Then paint with desired colour(2 coats) last coat with a hardener added.. You could use the cold gal, however it is not as affective as the gal dip Link to comment Share on other sites More sharing options...

Guest Aussie007 Posted January 27, 2011 Share Posted January 27, 2011 my axle,rims,U bolts were all rusted badly i used a nylon wheel on my grinder to remove all rust these things last yonks and only cost about $7 from hardware shops once all rust was removed i gave the rims (only parts i kept) a single coat with rust converter than two coats of black gloss kill rust paint two coats is all that is needed the pics show the before and after after 10 or more dips in salt water without trailer rinsing after use i also took the time to paint my new axle with the same kill rust brand paint as my axle is only the standard axle not gal and that to has no rust whatsoever on it either Link to comment Share on other sites More sharing options...
adkel53 Posted February 9, 2011 Author Share Posted February 9, 2011 I finally settled on an alternative solution after speaking with an experienced boater and metal work teacher. 1. Remove wheels and axle. 2. Clean off rust with a "flapper disk" attached to an angle grinder. 3. Treat cleaned surfaces (axle and hubs) with a rust converter. 4. Paint with Silvershield (courtesy of my friend) - an ormonoid based paint with aluminium flakes in it. One coat applied this evening, another tomorrow. 5. Reassemble axle (after cleaning up the U bolts and getting some new washers). Will paint the bolts with Silvershield too. 6. Remove hubs and replace seals and bearings. 7. Put tyres back on. 8. Return boat to trailer from its position on the ground in my back yard. Should be as good as new!! I'm tempted to paint the entire trailer but it will be a very shiny silver colour and look a bit "spivvy" I think. Maybe it will dull with age.

bisso Posted February 10, 2011 Share Posted February 10, 2011 Had a similar dilemma with an old trailer of mine. since you are going to the effort of removing the axle from the trailer, why not simply throw the old one out and replace it with a brand new gal one. i think i paid about $130 for mine and wont have too worry about cleaning rust off, painting it etc for many years to come. i did this and at the same time put new gal springs in as well (abt $70 a pair). My trailer is like a new one and i would not hesistate to do the same again. of course the decision on what you are to do it entirely yours.

adkel53 Posted February 10, 2011 Author Share Posted February 10, 2011 I looked at all those options Mick. The axle cleaned up really well and two coats of Silvershield have it looking almost new. It is still very solid. The springs are galvanised and are still in very good condition. I'm a pretty keen environmentalist and don't believe in replacing things that can be made safe and serviceable with a bit of effort and elbow grease. I reckon we need to reduce, re -use and recycle where ever possible, providing safety is not compromised. Kel Link to comment Share on other sites More sharing options...
