I've been successfully using Silicone spray to silence a number of creaks and rattles (posted in other threads). Yesterday I picked up a can of Jig-A-Loo thinking it would be the 'same but better'.

Well, I sprayed it into the crack around the passenger air vent, and also into the gap above the wood trim on the passenger side door. I noticed, while spraying, that I could see 'frost' on the plastics, similar to the frost you get if you shake a can of 'dust off' before spraying - it's the propellant reacting. Anyway, today, I noticed a serious discoloration on the air vent, and also - even worse - serious damage to the clear coating over the 'wood' trim.

I'm going to try buffing both with something (any suggestions? I was thinking using a Mr Clean magic eraser, or something) to see if I can at least partially recover from this.

I went back to using silicone, with no problems.

I'm going crazy trying to stop creaks, squeeks, rattles, etc. Now I'm damaging my car in the process!

 

acetone might frost certain lacquer or plastics
