Yesterday I applied a coat of P21S over Blackfire and the results were outstanding! I did the same last week and the results weren't as good. What I had learned was to apply the P21S in the garage as opposed to applying outside on a hot day. I also learned to apply only one panel at a time and then immediately buff off. The previous week the product dried in spots making the buffing job much tougher.
On another note I am now using the EF QD but is there another one that someone likes better? I know I can't use the Blackfire QD because of the carnauba topper. I appreciate any feedback anyone could provide.
