Awesome website here...tons of information!! I just purchased the Ultima spary and sponge block, but i have a really stupid question....whcih side of the block is suppoes to be used on the car?? on one sid eof the block ther eis a thin layer of a sticky rubber which measuers about 2-4 mm thick, and then the rest of the block is a sponge material. Do i use the sponge material on the car, or the harder rubbery side? :nixweiss
