aplying seam sealer

Any prep? Will it stick to weld through self etch primer with zinc?What is the best way to aply it onto a welded rough bead? A brush didnt seam to get into the nuk and crannies without geting it everywhere else?I thought maybe I,d try a small putty knife

Here is an article on the subject.. http://autobodystore.com/forum/showthread.php?t=7467

REMOVE the weld thru, it doesn't have very good adhesion properties at all.

Really you should prime it with epoxy or urethane and then after sanding and before painting do the seam sealer.

The easiest way to get the seam sealer into tight spots is to get a box of throw away gloves and go at it by hand. A finger fits into those spots better than a brush will.

After removing the weld thru junk,I would then "try" to smooth the weld bead out then apply epoxy which will go into areas the sealer won't and then apply the sealer over the epoxy after 24 hr. and finish it how you want.
I got a 3 year ongoing project primarily due to cheap seam sealer over etch primer and have seen the end results and damage from this OEM junk.
"If" the sealer had not failed and allowed water to leach under and attack thru the etch,I would have been done 2 years ago with a simple repaint.
