Interior plastics paint?

I dont know if all early A armrest bases were vacuum plated or not. Some may have been a low luster argent intead. If you remove one and look at the hidden side you would know. That side should look like new. Mexichrome is slang for silver spray paint like starter renew is slang for black spray paint LOL
Alsa Corp Killer Chrome is about as close as you will get to vacuum plating appearance from spray cans.
