J Trials 31 Posted November 29, 2009 Report Share Posted November 29, 2009 Got my Monty frame welded up, but it left some gold scorch marks so wondering about how to polish that back out so it's shiny again. I used some steel wool, but if that's what I have to do, I'll have to sit there all day. ThanksJ Quote Link to comment Share on other sites More sharing options...
Revolver Posted November 29, 2009 Report Share Posted November 29, 2009 Buy a buffer pad for a drill or angle grinder. Quote Link to comment Share on other sites More sharing options...
liam-pantera Posted November 29, 2009 Report Share Posted November 29, 2009 (edited) use acetone to remove any residue left by the weld and then finish it with either a steel brush or a fibre wheel its what we do at work when welding aluminium .

ThanksJI weld ali and stainless all the time at work the best thing to use if u can get it is pickling paste its slightly acidic so wear gloves when used but it will remove all heat marks from the weld area with a light buffing it will be as newoh +1 for the acetone post buy liam that works too LOL Edited November 30, 2009 by scotty007 Quote Link to comment Share on other sites More sharing options...

eep803 Posted December 1, 2009 Report Share Posted December 1, 2009 Just a wee note on "pickling paste". Its a tad more than slightly acidic. Its very acidic, a mixture of nitric and hydrofluoric acids, and your skin isn't waterproof to it so if it gets on your skin it soaks right in like moisturizer then burns you from the inside out. Businesses need a license to use it so I'm not sure how easy it'd be to get hold of. But if you do, full spec goggles, gauntlets, apron, no exposed skin etc and a bucket of clean fresh water at hand to dunk yourself in.
