In '97, I did a '32 5 window that went to compete for 'The Ridler Award'.
http://en.wikipedia.org/wiki/Autorama
This is from 'Hemmings'. (paraphrased)
"It’s said, with considerable justification, that having a hand in building a custom car that wins the Detroit Autorama’s Ridler Award can make a career for a designer, fabricator or painter.
Winning a Ridler can set up a shop for life, so to speak, but even making it to the finals is a resume builder. Building or painting a Ridler Great 8 finalist can be a feather in any customizer’s cap. As mentioned, all of the cars were built to a level that to my eyes surpasses the attention to detail associated with production cars like Rolls-Royce or Ferrari." - Ronnie Schreiber
The car made it to be one of 'The Great 8' finalists.
Anyways, the owner did something that I had never seen, or done before, to his tires.
First, he washed them with a 10% vinegar to water mix, followed by a good rinsing. If the vinegar mix is not completely rinsed, it'll leave a white residue.
Then, he used 'Future Floor Polish' on the tires. A small bottle that he kept applying multiple coats with, until he had used the whole bottle.
Gave the tires a nice shine that was a bit more than a matte finish, but not so shiny to look cheap.
And, throughout the rest of the show season, all he had to do before each show, was to wipe them down. They looked like they had just been treated.
Seeing what these 'show' guys have to go through each & every time that they set up the car, this was one less step that he had to do, because it lasted the whole season!
I was impressed, but, hey, this was a show car. The first year, the only mileage put on it, was on & off the trailer!
I was also skeptical. How well would that stuff last on a street driven vehicle? I had to try it.
Well, that stuff lasted almost 6 months! Multiple car washes, hundreds of miles!
I could go to a wand wash & hit the tires with that high pressure water, drive it out, wipe 'em down, & they looked like I had just applied the stuff. Amazing!
I now do this to my tires when they are brand new, & once a year in the spring.
But, because it takes a while for it to dry, it's kinda impractical on a weekly basis, so I keep 'em touched up with that Meguiar's stuff.
Here's some other uses for that stuff.
The model building guys seem to like it.
