Hi Larry,
if it's tar-related any solvent will soften and attack the under coating. Try
a product like Varsol, or use thinner, maybe engine cleaner. I've spent MANY
hours stripping down undercoating off the frame, the inside of the bonnet, the
firewall, just about any inside panel on my GT6. I applied the solvent [for
me, thinner worked OK] then let it soak in for a while and scraped it of with
a putty knife, wire brush, or brushed it off with an old brush. Some of the
undercoating needed to be scraped of with an exactor knife. It's a tedious
job.
Pads for the drill or the dye grinder [Roloc, 3 M products ] did not work for
me for this job because the undercoating is too soft. Neither did sandblasting
for the same reason.
If the coating is non-tar related, for instance if it's gravel guard, then you
will have to grind it off, using whatever method works for you, wire brush,
3M.
Good luck.
Cheers

Subject: undercoat
Is there an eazy way to remove this stuff. Some places it's over 1/8 inch
thick. I have a pad, for the drill, that works but the pad wears out too
fast.
It's like a brillo pad coated in plastic or rubber. It looks like I would
go
through a dozen pads and burn out my drill doing the complete frame. Useing
a
putty knife is a good way to hurt yourself.
