Is there any easy way of removing what looks to be the residue of the glue from the roof numbers of my long time retired cop car? I managed to scrub one off with Simple Green, numerous clean paper and cloth rags and about my whole years allotment of elbow grease.

I have been trying from time to time on the other 2 numbers, without any luck. I was thinking there had to be something, short of rubbing compound to get it off. I don't want to damage the paint any more than I have to.

Depending on the adhesive used, I've found Goo-Gone or 91% isopropyl to be effective.

Goo Gone and Alcohol are having no effect. They both just feel slick as snot and the rag comes away clean.

I don't see how I got that first number off. Maybe there was enough dirt on the surface that it acted like a rubbing compound. It still looks like clear coat where the number was, and there are only 1 or 2 specks of it left.

I always thought it was just some staining on the roof. Then a few months ago, I was up on top of the house fixing the TV antenna. I looked down at the car and it sure looked like the last 2 numbers of when the car was active. You can see ghosts all over the car where they were had been removed.

I don't know why I'm even worried about it. It's not like it is some kind of show car. It seems that every body panel is a different color of white. Some creamy, some chalky, some with clear coat, some without.

Having had to remove sticker residue and staining from about a dozen P71, both black and white, I can tell you that there is no one solution that works in all cases. I agree with RF Overlord that in most cases Goo Gone and Isopropyl alcohol are what I reach for first, alone with magic eraser sponges. This will usually do with little numbers and small decals which don't have the adhesive of the bigger ones. If stuff doesn't come off instantly, get out your heat gun because the adhesive used for vinyl film hates heat.

Sometimes, I've seen them clearcoat OVER the top of decal and then you're screwed and you'll see ridges, buttes and valleys where the stickers were. Try some polishing compound which usually works well on things like LightBar stains on the roof.

With black, you'll always have some ghosting so unless you're okay with it, or you're ready to re-paint, you've gotta become okay with it. With white, I've learned that as long as you're not peeling and patchy, you're doing pretty good. I've sold a bunch of P71 with iffy paint and the buyers don't mind as long as they're not peeling and patchy. I've developed a rattle-can method that can do a whole panel of performance white and get it to match pretty well, with only a bit of uneven sheen on the gloss topcoat.

I just sold another one this week, entire front hood was gone, both c pillars and two spots on the rear quarters... in other words your typical peelformance P71. Looked pretty good when I was done and most buyers of these cars are like you, they're buying the horse for its muscles and stamina, not the pretty bows in its mane.

My car number is 052, district 13 which is Riverside County Sheriff. Number and glue are long gone but the ghost is still visible in the right light. Glue has eaten into the clear coat so it is not going anywhere.

I use a rubber decal eraser wheel for the most stubborn residue.

Someone once told me to use acetone. Takes it right off without damaging the paint. I've not tried it myself.

Oh acetone will take it off alright... and clear coat, and base coat, and primer. I botched one clear coat badly by using acetone too long and too much. Turned it gummy and cloudy.

Well yeah, acetone is paint thinner. Naphta spirits is gentler on paint and will dissolve most adhesives.
