Acid Rain etching. Can i do this to fix it?


TRD468

Recommended Posts

Hey guys, i recently purchased a TRD Aurion 3500sl, and it had been slightly neglected by its previous owner. The car is clean but to a detailers eye it needs alot of TLC. Anyway, i have some acid rain etching on the shinny Black plastics on the B pillar/doors. I have already tried rotary buffing with a compound but i haven't managed to remove the defects. I was thinking of colour sanding with 2500 uni-grit sand paper, but i'm not sure if it i will damage the pillars. Are they painted? do they have a clear coat? or are they just clear plastic over a painted surface? I have been using the uni grit on some parts of the car due to more severe defects, but i just wanted to double check if i am able to sand down this surface, and then buff it to a shine, as you would with the other painted surfaces. Also, my rear spoiler has suffered quite badly from this as well, and buffing has only removed small amounts of etching. Can i sand these "plastic" parts too? i know the ZR6 aurion you can't as the plastic for the spoiler is much clear, and it will make the paint more transparent when sanded down (for a silver or light coloured car), creating a blotchy effect in the sunlight. I know the material is different for the TRD but i don't want to risk it, until i know what sort of material was used for the spoiler.

Hope you guys are able to help! :)

Cheers, Anthony.

best way is to use the 3000 grit paper to be safe. are you sure its a rotary or is it a random orbital. random orbitals dont put enough heat on the clear coat to cut it down. some panels can be plastic wrapped... nothing u can do there.

I tried sanding it today, i rubbed it back very lightly, but it seemed to have some depth to it. plus it looks like as if it has a clear coat as the residue was milky. I managed to remove some etching but it looks to have damaged the surface. Plus my rotary buffer has decided to not work anymore, so i used my dual action polisher to buff it up. I may have to invest in some new pillars!
