Yes, I am a cheapskate to the extent that I want the best price for the quality level that I desire. 
I have an 04 WRX, and a friend just bought an 06. I'm hoping to be efficient and choose products that I can split with my friend for our two cars. Both cars are black.
I have just ordered the CG clay bar and blue wheel cleaner yesterday, and am today considering that maybe I should also get some upholstry shampoo and sealant.
My current arsenal is:
-costco MF wash mit
-costco MF
-bunch of terry cloths
-silicone "blade" thing for drying
-costco car wash soap. I think Zaino or something? It's blue, smells nice, and lathers well
-Meguire's tire gel
-Meguire's swirl remover
-Meguire's polish
-Meguire's carnauba, the solid stuff in the squat cylinder
-Nu synthetic wax (about 5 years old)
My paint has some light swirling. I did a bit of treatment by hand with the Meguire's swirl remover on the hood, followed by some polish and Nu and it looks great. My current plan for sometime soon is:
-wash twice
-clay
-swirl remover by hand
-polish by hand
-apply sealer
-wait a few days, wash again, apply carnauba
What I am wondering is if you would recommend:
-CG "Magic Seal - PREMIUM PAINT SEALANT SYSTEM(1 Gal)" for sealing my paint after the polishing step, or can I just keep using my 5 year old Nu? Will either one accept a carnauba coat well?
-"UP 500 - Upholstery Shampoo & Cleaner (1 Gal) " for scrubbing my interior? There are some spots that the previous owner got in there, but it is a dark interior so if I don't manage a perfect level of cleanliness it will be ok.
-Should I dilute the CG blue wheel cleaner any, or use it full strength (assuming wheels are reasonably maintained)?
For my friends brand new 06, can you suggest if he should be set doing just:
-wash twice
-clay
-apply sealer, with optional carnauba sometime later?
Or do you think he should also go through the trouble of polishing before the sealer?
One final question - is there any reason to use these little foam applicator pads for wax, or would I be fine using a MF cloth? Has anyone compared a foam applicator to MF on the scratching-a-cd test?
Any other tips?
Thanks!
Adrian
