I have used their spider One Step compound (similar to their laser buff compound), pro-polish and Finish polish. I have used them in the sun in conjunction with Menzerna polishes. These are one of the easiest compounds to use with a long working time.
I agree that Spider One Step is probably the mot versatile (and my favorite). I was able to remove scratches and swirls with an orange pad. It then breaks down to a nice finishing polish. Dust is low compared to Menzerna and definately to Poorboys.
Finish Polish is very low dusting, if any, and sets my car up for LSP ready. Again very easy to use and long working time.
I, and others here, have really been impressed with thier newer sealants. I have tried FS Seal. It has really impressed me: I have had it on the Jag for a month now with all the rain ect, it still has very tight beading, and is one of the slickest feeling sealants I have used. It claims to help against dust attraction, and so far it seems imo that its true (especially after driving the car, the dust seems to slide off).
