ragman- Welcome to Autopia and congrats on your PC purchase. I'm a big Griot's fan/longtime customer, but their polishes and waxes aren't too hot. The best thing about Griot's products are easy ordering and the foolproof #1-#2-#3-wax system. And the #3 is VERY mild. In fact none of them will do much for heavy swirls or scratches unless you spend a LOT of time on it. Griot's polishes are quite hard to remove after you finish PCing; you'll really need some Final Inspection QD and microfibers to get all the residue off easily. I've used them quite a bit and really recommend that you go with something else. Just WHAT will depend on how bad your imperfections are, but I'll bet you'd be MUCH happier with products from 3M, Meguiar's, Pro, etc.
For wax, you can DEFINITELY do better than Griot's stuff, even if it does win shows. The PC works fine for applying ANY wax or sealant, liquid or paste. Again, it depends what you're after-incredible looks, durability, ease of use, etc.
