seam sealer or undercoating

[dfink]

The forums have gotten so large and filled with so many words that simple searchs seem to yeild hundreds of pages of posts with very little relevent to what a person is looking for anymore. I am sure there is a perfectly good answer to this if I use the magic combination of words but someone can answer and save me the 4 hours of reading about cleaning wheel wells or removing seam sealer.

Anyhow welded in the cage and at both front and rear fenders the coating in the wheel wells was burnt off by the welding. The wheel well coating doesn't appear to be a tar based undercoat like that found on some cars. To me it appears closer to the seam sealer removed from the inside. Should I just brush off the burnt material and cover with seam sealer or is there an actual wheel well coating, What is there peels off like some sort of latex / rubber material.

The wurth sks is pretty close also. I think 3M has a similar product, the name of which I can't recall. The wurth stuff is water based, which makes it a breeze to spray (I used their "schutz gun") and clean up.
