Feltpen Fadeout can be used with much success on egg staining and splatter. The high sulfur content in egg yolk can turn to sulfurous acid as it dries, and if left long enough can actually strip paint from powder coated or prepainted metal sheeting. Once dry, egg yolks can set as hard as concrete. Egg splatter does not usually affect emulsion, oil or acrylic paints. Egg staining is really only a visual problem on these surfaces as it turns grey to black marks if left untreated.

3 Golden Rules
1) IF GRAFFITI IS NOT COMING OFF EASILY, YOU’RE DOING IT WRONG! You may require a change of tact or use of another product.
2) IF YOU CAN’T REMOVE A LITTLE BIT OF GRAFFITI, THEN YOU’RE NOT GOING TO REMOVE A LOT! TEST FIRST before applying product to an entire job. This way you can determine if you’re on the right track before embarking on full scale removals.
3) IF YOU’RE WORKING HARD, YOU’RE DOING IT WRONG! Forget the scrubbing, blasting and any other abrasive measures. Put simply, either your products are working or they’re not. Any problems can be taken care of with the right technique.
