Google know everything
so look under your engine cover and check the markings, then google to find out about the material used in the construction
“PA“ is a polyamide class material while the “6“ specifically indicates its Nylon and the “GF15“ further indicates the material is 15% glass fibre reinforced.
And PA6-GF15 softens @ 195C & melts @ 225C while it has a flammability index of HB which means it burns but is considered self extinguishing (and is the lowest least flame retardant UL94 rating; whatever that means).
So in theory PA6-GF15 can be repaired using a modded soldering iron and some Nylon cable ties (with a bit of fibreglass if you’re pedantic).
As to issues of stripping paint, Acetone is supposedly safe to use on Nylon. Considering many other paint strippers require using a Nylon brush, presumably such paint strippers could also be safe to use on PA6-GF15 Nylons.
Me, I haven’t tried to ever strip paint off an engine cover but I’m sure many panel beaters/paint shops have done such so you could always talk to one near you if you don’t trust google (and why would you).
