How many of your guys have used there product compared to another brand how good is it? Ive looked at so many different brand and know most work well but some better than others. Im looking for the brand the will supply me with the best products no matter the cost. My main question is how are the compounds and sealants, I would be doing a full paint sand for eveness and didnt know how well they would bring the shine back and get rid of the markings from the process.
