If you use the yellow cutting pads or the orange compounding pads, be sure to follow up with the green (or blue or white) pads. The yellow/orange don't leave all *that* great a finish no matter what product you use with them.
I always do best by fixing the marring, getting things seemingly perfect, and then doing some final burnishing with the white pads and a very mild polish. Yeah, it really does make a difference
The Cyclo isn't all *that* fussy about products, but it does *NOT* work well with KAIO, it flashes that product too fast resulting in a very tenacious residue. Also, I'd never use it to apply KSG, it'd result in far too thick an application.
I dunno which products I'd recommend as my favorites via Cyclo for correction like your Subie (and for use before Klasse) were discontinued a while back and are now hard to find (3M PI-III RC 05933 and PI-III MG 05937). The 1Z High Gloss, which I *DO* really like via Cyclo is probably too mild for what you're doing, but it might do the job :think: I'd probably lean towards something like Hi-Temp Heavy Cut (much milder than it sounds) followed by the 1Z High Gloss.
Oh, and I sure wouldn't top the KSG with any wax until you get at least four (better yet, six) layers of KSG on there. But then I've quit topping KSG with wax altogether as I like to just keep adding KSG as needed. I used KSG on my last Subie ('02 WRX) and it worked out great, even used it on the black plastic trim.
