We have a few handprints on our Pajero that appear to be from sun block. Does anyone know way of removing these without risking damage to the paint/clearcoat.

Regular car wash and a sponge foam doesn't seem to remove it.

Any suggestions?

Try just using a paste polish if that does not work use a mild cutting compound then re-wax. Use the cutting compound sparingly as you don't won't to go through the clear coat.

^ Pretty much as above. I had exactly the same problem just a few weeks ago - white "fingerprints" on silver paint work. Came to the conclusion with some googling that they were caused by sunblock from fingers causing etching. Light cutting compound from supercheap, a microfibre cloth and some elbow grease and they've mostly disappeared. I say mostly because I noticed while camping a couple of weeks back that they still show a little in torchlight - I'd guess a bit more elbow grease would get rid of that, but I'm not too bothered by it as long as they're not showing in daylight\normal use.

TBH I don't think you will get it out, sunblock penetrates right down to the metal primer, i've had the issue in the past and wasn't able to resolve it without taking to a panel beater and getting the area stripped back and re-painted.

Polish the entire car with sunblock.

OK, thanks. I might just take it to a professional. I won't bother with a repaint, but if they can polish it out.

Sunblock is aggressive stuff. It attacks one of the clear coats used on boats and one of the plastic used in boat windows as well. And to think we put it on our skin.

Gee, didn't know that about sunblock. Something to watch out for.

Prepsol (Wax and Grease remover) - good for getting off tar spots too
