Sent you a PM Nightcruiser.
As for getting the plastic off, it won't/can't form a molecular bond with the metal, so leave it hard & peel it off in chunks. You
REALLY don't want to melt/soften it again! I've found that leaving it to cool/get cold & then picking/peeling it off in chunks using a blunt tool to prise up an edge works best for
plastic that's melted on. Once it's cool, most plastics will come off fairly readily, but it is a painstaking process!
If you melt it or soften it again, it goes all sticky and gets
EVERYWHERE, and sticks to you and everything else it touches, tripling the mess!!
Still, plastic is
far easier to get off than the exploded guts of old road-kill once that's baked on!!
That stuff can
STINK, I've had people
RUN away from my vehicle due to the strench of burnt on road-kill; and I kid you not, on one occasion that happened to my 4WD Truck, it stunk so much that I whimped out, and just cut the exhaust right off, tossed it (a looong way off too!
) and replaced the whole exhaust rather than putting myself thru removing the baked on intestines & putting up with the smell until it cleared!
Just imagine this swollen & decaying donkey going '
BANG'
Peeling 'hard' plastic off is
EASY by comparison!
Enjoy!
