My friend shook a container and about 6 drips of protein landed on his rear bumper. He drove home and 15 minutes later he washed his car only to have some weird dots on his paint in the areas where the protein landed. He has a brand new car and it is noticeable in certain light situations.

So far he has tried to wash it with no luck.
Wax it with no luck
Turtle Wax tree sap and tar remover with no luck

Anyone have any suggestions?

 

Hard to say without actually being there to look at it. Maybe you can post up pictures?

If it was my car I would wipe it down with a rage of mild solvent to see if it removed it. If not, go on to lacquer thinner. If one of those worked, then I would buff back what i scratched up/dried out with the rag/lacquer thinner.

Basically, if I were you, I would bring it to a detail shop and ask them to look at it. If they aren't complete ******** they will fix it real quick for free or maybe $20 bucks.
