I have had many tire shine sprays and foams. Most times (ie 8) could be his tires so 2 times Edit and after a week of fun was over. You have to shell out for usually 9.99 to 12.99. The gel of Meguiars costs 2-3 euros more, but you get it many times more offered. On my 3rd photo you can see how little gel I needed tires for 8 (!!!). Time I can not judge, is of course grudge. Buy recommendation!
