The stuff you use is called FMC
You tell the guy at the paint place your
repairing a Fiero or a Saturn, The guy that
sold me my repair stuff told me when
ever repairing this plastic you do two things
1... You put a diamond around the crack
with a die grinder, this allows the plastic
to flex and not crack.
2... when your done with the repair before primer and paint. you hit the repaired
suface with the palm of your hand. If it
recracks you didn't mix the stuff properly.
If it sustains the impact you mixed it correct, I had never repaired a Fiero before
but I found it easier then Fiberglass.
And the guy that painted my car is PPG Certified and his oppinion was with a little
patience and some minor guidence it's easier then Metal.
By the way I had a crack in the door
a crack in the front fender and a corner chiped out of the driverside door.
So far 6 months later and know whitness of
bad body work.
