The detailing products in this ad are all Advance Auto house brand stuff, but the other products are WELL worth it. I guess that house brand stuff might be ideal for a cheap detail on a beater, I`ve personally had no experience with any of those products though. $3.48/can + tax for R-134a refrigerant is about as cheap as it comes. Check out Advance Auto Parts - quality auto parts and accessories before wasting a trip to your local store. I do believe AA runs all these ads nationwide, but I would confirm that by checking out your local ad online first.
