Review on Uxcell Sponge Compound Polishing Buffing by Arun Siddiqui

Great for ceramic coatings on cars but the black foam is very thin and peels off easily. You can coat 1 whole car per block before the black foam comes off. So if you coat 2 layers you need 2 blocks and 4 blocks for the SUV. Don't even think about using them for marine grade or premium heavy duty solvent based coatings like CP.
