cute wee gem Posted March 13, 2012 Share Posted March 13, 2012 Pretty crap pic but you can see where the top of guard is sealed against the other panel What's the best way to stop paint cracking in these joins? I don't want to weld the panels on. I figuered my best bet was to cut the sealer as low as possible and por15 over top to prevent rust if water pools in the join. What have others done?

cute wee gem Posted March 17, 2012 Author Share Posted March 17, 2012 yep, a lot of aussie gems get welded up Quote Link to comment Share on other sites More sharing options...
Bling Posted March 18, 2012 Share Posted March 18, 2012 Interesting.... I got told its easier to cut holes in the top of the guard to fix rust rather than take the guard off. I need to fix rust in that area so may just weld it up... Could you just put a bead of decent sealant in there that is paintable? The stuff with use at work, Silaflex MS is flexible, lasts and can be painted over. So even if you just brushed some paint on the top of it, if the paint cracked it won't get past the sealant.

cute wee gem Posted March 18, 2012 Author Share Posted March 18, 2012 Sealer itself doesn't crack, just the paint on top. I'm not worried about water getting past the sealer, it just looks horrible when the paint turns to shit on top. Quote Link to comment Share on other sites More sharing options...

nzstato Posted March 18, 2012 Share Posted March 18, 2012 I take it this area was originally lead wiped? Have you considered fibreglass filler or metal impregnated filler (i.e. newtech), it would be less likely to crack compared to a sealer or regular bog Quote Link to comment Share on other sites More sharing options...
sr1600 Posted March 18, 2012 Share Posted March 18, 2012 Not really the answer your looking for and assuming you dont want to see it I would get a little brush with some gloss black hobby paint or the like and paint the sealer down inside the groove with it will be way less noticable and easy to do again anytime. If the sealer is black you wont need to do it again. Quote Link to comment Share on other sites More sharing options...

Bling Posted March 19, 2012 Share Posted March 19, 2012 Try spot welded, in places I can barely get my hand. So not much chance to drill the spot welds out without a nightmare. I'm sure it's possible, but fuck that. Quote Link to comment Share on other sites More sharing options...
Spencer Posted March 19, 2012 Share Posted March 19, 2012 I have seen a couple of restoration shops fix up panels like this (they had removed the factroy lead as it often rusts underneath) they welded the seam up and used a 3M exopy to fill the rest, then a skim of a decent filler like rage gold, Upol etc and I doubt it will crack.
