on the zoopseal website it has a step by step application guide on a set of rims, very detailed. as for the heat build up i use a large machine the gives about 9000sfm w/10"wheels. i get a lot of heat. i use leather palm gloves and when it starts to get hot through the gloves i know i am about right. the trick is to get the part hot and use the compound to do the work. as the compound is grease based it will melt away and the grit will start to cut. as for pressure on the wheel you will find the sweet spot with time. hang on tight and tear it up. polishing is not a science it is and art, and you have to find the technique that is best for you and the equipment you have. best of luck bro, and keep us posted.
