This might be a silly question but can't seem to find the answer when searching - does anyone know what actual material the 85-90 firebird/formula bumperettes are made of? are they some kind of synthetic rubber or plastic/vinyl? Reason I am asking is just looking for the best way to take care of them/prevent drying and cracking. I was thinking normal black trim protection products, but was wondering if something like mink oil might be better. Any input is appreciated!

 

I realized after posting this might fit better in auto detailing section, feel free to move if needed

 

Just molded black vinyl/abs/plastic, something like that. They fade, crack, dent, bend, break, etc. Their shape is convex on the outside, concave on the inside, not padded and not rubber. Your favorite exterior trim treatment product should be fine.

I thought I had pictures on my laptop of a pair I took out of a spare bumper cover and sent to a member here, but I'm not finding them, so maybe they're on my phone. When I find them I'll post them, if someone hasn't posted pictures by then.

 

thanks for the info!

 

Bumperette ? Are you talking about the front and rear , (rubber) bumper cover? AKA Facia. It is likely has "PUR" molded into the back side of it, in difficult to see raised letters. PUR is Polyurethane.

 

The bumperettes are the black bumper inserts used on later year Firebirds and Formulas that do not have the lower ground effects. The Trans Ams didn't have them.

They are located on the front and rear bumpers of the car, as shown below.

 

Look for the letters molded in the Bumperettes. .Then try googling them and the word plastic and or rubber.

Beautiful car, Codyman!

 

I wish it were mine. Those are just the pictures that popped up when I looked for the bumperettes! I actually think that is two different formulas in the pictures… one has a pin stripe, the other doesn’t.
