I'm getting small brown dots on the starshield that do not wash away. It looks like a stain from tar. The tar wipes offf the painted surface but leaves a small stain on the starshield. Can I try Bug & Tar remover? It looks awful.
How exactly is "starshield" different than the 3M product? Same stuff with a different name?
I have the 3M invisible bra on our car, I have used bug and tar remover and it worked fine, didn't hurt the shield and pretty sure it removed all of the stain. But the car is black so tough to say 100%...
Back in the 70s, we all had little dispensers of MEK and Benzine at our desks and would indeed wash our hands with the stuff. Around 1979 I think we started hearing warnings about MEK.
I also worked in a shipyard building oil tankers in 1976. I wore asbestos clothes and used asbestos gloves. The gloves would wear and fray after a day and you could clap your gloves together and make a snowstorm of asbestos in the air. We had no idea.
By the way, I still swear by Bestine as an all around solvent for removing almost anything without harming the surface underneath.
Now that you mention it, I noticed a couple yellow spots on my friends starshield (Silver car). I've found a little bit of wd 40 is good for removing tar, just don't use it anywhere near the edges, it'd probably lift the film.
