Brent,
I read the tech sheet.
I would read the can and follow the reducing directions to the tea. Tech sheet says not reduce more than 5% but if you do an "Accelerator" MUST be added.
Be interesting to find out what happens if you reduce more than 5% and don't use the accelerator?
I said this once before, I think 10% is the max reduction recommended by "most brands" of 2 part clear urethane.
That product is a 2 part urethane clear and it should be fuel proof?
Wax will help.
One thing though, it does say that the product is "Specifically formulated for the mobile repair industry."
There are independent touch-up vendors who are contracted by auto Dealerships. Their tasks are to bring back to life small areas on vehicles that require paint repair.
Most of this work is on the front and rear bumpers and the painting of aluminum wheels. There's plenty of guys doing this mobile thing.
The wheels are generally an entire repaint but the bumpers require blending. This product "Formulated for the mobile industry" would be those guys.
BTW. These guys that do touch-up paint and frequent Dealerships know their product and have a good deal of ability. They can earn two grand a week with the right accounts.
So can a qualified pinstriper.

Good luck with that product.
Charles
