i would like to have some numbers made for my car for autox use. but, as we all know the doors on 4th gens are fiberglass and rules out magnetized ones. anybody know of somebody that makes reuseable electrostatic vinyl numbers? or other alternatives to staying with the painters tape method? what do you guys use?

A couple of years ago I had a local sign/banner shop print up some vinyl ones for me.

Many 4th Gen owners I know put their
magnetic numbers on the rear quarters. Class letters many times go in the sail panels.

They have made several sets of numbers for me over the years.

There is one company, I think Solo Speacialties that sells numbers and letters for racing.
