Remove paint from lexan windows

The previous owner painted class identifiers on the side lexan windows of my Henry J. Is there any way I can remove them without damaging the lexan? I don't have any idea what paint he used.

Enamel paint like found in spray cans won't usually stick worth crap on smooth lexan. If the lexan has been roughed up before painting, or the paint is compounded for lexan-type plastics, it'll never come off w/o marring the window.

I have no experience w/polishing lexan to remove marring- possibly that's an option.

How to remove enamel paint from clear Lexan window

7 years later....may have been some changes in Lexan or enamel ingredients?

Had a similar problem on my 1991 ex drag car. I tried many different things on my clear Lexan/Polycarbonate windshield (no coatings etc.).

This worked good:

1. Get a new steel putty knife (sharp) and a 1" foam cheap brush and Blue fat masking tape (to protect surrounding area), windex window cleaner, paper towels.
2. Go to nail polish section of any big store. Look for nail polish remover (npr) -- think of it as Strong Paint Remover.
3. Found some Gel remover called "New Acetone Gel Formula" , comes in a small jar, $4-$5. Ingredients: Acetone, water, carbomer, PEG-15 Cocamine, Linoleic Acid, Dimethicone, Red #33. Liquid npr m-a-y work okay on horizontal surfaces..... may need to keep area wet?
4. Went home and Taped off area with Blue fat masking tape.
5. Applied a THICK COAT of gel since I had 2-3 coats of enamel on the Lexan windshield. Got some excess Gel on areas next to numbers. Temperature outside was 65 degrees.
6. Wait 5 minutes.
7. Came back and used putty knife. Paint came off fairly easily with just light to medium pressure. Be careful -- easy to scratch! Missed some tiny spots....... reapplied.
8. Used regular windex window cleaner --about 3 times -- to clean up the area. Acetone Gel didn't seem to harm or cloud the Lexan any. Looks real good.
9. Will use a Headlight restore Kit....or toothpaste to polish small scratches on window. ChrisFix has a good youtube video on headlight cover (Lexan) polishing options. good...have fun

Before i would use anything unknown i would find out if the product in your windows is actually lexan or is it some other form of plastic since some really dont like certain cleaners. You may not want to use anything with alchol or some of the other common solvents.

If your not real sure the common cleaners that are used for this type of job. Have you tried taking them out and cleaning them with good old soap and hot water to see if you can rub the paint off.

If all else fails you can buff the numbers off with mirror glaze fine cut cleaner or other similar rubbing compound that is fine enough to polish the numbers off without fogging the glass.

A hair dryer can also help if your just trying to rub it off in the car. I would be careful if using an heat gun.

Here is a link to a pdf at the bottom they talk about products they use for cleaning different types of marks.
