‘Throw-up’ or ‘Slap-up’ Stickers are commonly made from postal form stickers and delivery stickers free at the USPS Stores. Stickers can be coated or uncoated and come with a variety of adhesives. You generally need to remove most of it by scraping with a metal or plastic scraper and then brushing on Sensitive Surface Graffiti Remover generously, and agitating until the adhesive begins to dissolve.

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.
