Polyurethane spray-foam is a very adhesive product. It’s unlike any type of paint products. The normal cleaning method are useless when a vehicle is heavily damaged with this type of overspray. The clay-bar is the preferred method to remove paint overspray. This product mills down each paint dot until it’s in a liquid form. The problem with spray-foam is, it does not mill down layer by layer like paint does. The method demonstrated in my videos will remove 100% of the overspray without using any compounds, solvents, chemicals or wet-sanding. We also give a guarantee on all work performed on your vehicle with video documentation.
