I feel your pain, I was really serious into detailing for years with my 1991 3000GT VR4. Here are the products I know that work:
1. Zaino. Best long lasting polish on the market, hands down.
2. Blackfire. If you have a black car, or even if not, this stuff is amazing. Wettest shine out there, just doesn’t last as long as Zaino.
3. Crystal Guard. If your paint is old (like mine), this stuff fixes a myriad of issues. Think of it like glass particles liquified. First time I used it I burst out laughing cause I couldn’t believe how well it worked. Stuff is from Japan and hard to find, but worth it.
4. Dawn. Only way to get all crap off your paint. Strips all waxes, oils, and polishes off. Good for complete washdowns when you’d like to try a new combination of products on your paint.
Other tools:
1. Clay Bar. You have no idea the amount of crap in your paint till you claybar it. You’ll be shocked. Takes forever and is difficult, but it’s really the only way to truely have a good base to start your polish on
2. Orbital Buffer. Get a Makitsa…spend the money and do it right. Don’t get a crappy one.
3.properautocare.com – great place to buy stuff for care care. Good forums too.
4. Paint temperature thermometer. Polish and compounds don’t work 1/2 as well when your car has been baking in the sun for hours. Paint is like reverse skin pores. When it cools down, it opens up and chemicals can penetrate into the paint proper.
4. EZ-UP Tent. Great to put over car if you don’t have a garage while you detail.
5. Never-Kink hose. Best hose to have, can find at home depot.
That list should make your car look crazy good. My recommended process is:
Dawn wash, dry, clay bar, dawn wash, dry, Crystal Guard, Zaino/Blackfire, Zaino Z-6 finisher. End result, car is clean as possible and has good long lasting polish protection for at least 1.5 months (with bi-weekly NON-Dawn washes, and a layer of Z-6 finisher to keep it sealed).
Let me know how that works our for you.
PS: Invest in a car cover, a proper one made for your car. Good ones cost ~$300…expensive, but makes all your detail work last at least 2x longer.
