TCM - We should talk and compare notes. Just got my Diablo, but had 355 before that won 7 major concours and P Turbo before that..many wins. Have more product in my garage than Pep Boys.
Your comments are 100% correct. I too have the Zymol Vintage for $1400 (got it as a birthday gift)...
Sealers/polymers last forever, are shinny but can leave the car "sterile" where it looks "plasticy" (no such word) and lacks depth.
I have found good luck with Klasse as a base with P21S topper... Until just now.
The car I have was originally owned by Phillip Benton, Jr the Pres of Ford Motor Co. It was acquired by the collector Tony Picarilli and I purchased from him. Anyway..... Tony has about 40 cars and a staff to take care of his cars. The car is stunning and I asked what kind of wax he uses. Turns out he has his own private blend made for him. He gave me a bottle of it. It has carb and poly in it with a very slight bite. If you use it with a buffer it will clean, use it by hand it will gloss only. Wipe on Wipe off.
We turned out to be good friends and speak a couple of times per week. He is sending me a gallon and if you PM me with your addr I'll send you a small 4 oz bottle to try...
Also here's another tip...on leather I've tried everything and ended up with Leatherique as my favorite. Know George, the owner, from car shows. So what does Tony use? Interior looks like new, literally. Mink Oil only. Comes in a can (not kiwi like for shoes) and get via mail order. Stuff also is killer.
Question - On OZ wheels, the outside stainless lip....is it clear coated?
