I have been visiting autopia for some time now and have been detailing part-time now for a few years (or at least I thought I was detailing). I have learned so much over the past 6 months and have progressed in my detailing skills. I believe I need more confidence when it comes to swirls. Would like to eventually get a rotary...down the road, in the mean time getting comfortable w/ my pc. My question is how do I know what products generally contain fillers? Products I normally use are ssr 2.5, klearkote vanilla moose hand glaze, aio, and poorboys sealant/wax. Any help would be appreciated.
