The Gtechniq AP3 Dual Layered Soft Foam Applicator will allow you to safely apply virtually any of your favorite products. Use it with waxes, sealants, coatings, etc. with fantastic results. The AP3 Dual Layered Applicator is very soft so it's paint safe. It measures 10cm in diameter, which is almost 4 inches, so it fits your hand perfectly. You can use it to apply your favorite wax or sealant, but where this applicator really shines is with thicker coatings and even polishes. It helps keep more product on the surface so it doesn't absorb into the foam. If you are looking for a soft applicator pad to apply various products, the Gtechniq AP3 Dual Layered Soft Foam Applicator is a great choice!
