Ok here goes, what is the difference between commercial grade vinyl for signs and vinyl used on cars? I was looking for some vinyl with a gradient from one color to another and I was told I should look for automotive type vinyl. I was also told it has a much worse warranty?
Also does anyone use vinyl prep before painting vinyl with One Shot?

The "gradiated" vinyl is screen printed with the "effect". ALWAYS make sure you get the BEST grade (2 mil.)of this kind of vinyl, as it holds up really well. K&R RAINBOW makes this stuff. I've had good results with it.

Iv'e only heard "commercial" grade used in reference to reflective vinyls and think it may have to do with the strenght of adhesive (but not sure)
The way I understand it there are two types of vinyl (not talking about polys etc.) Calendered is manufactured by stretching and mushing the vinyl to it's final thickness. Cast is poured right to thickness from its liquid form. Therefor the cast is more dimensionally stable right from the get-go ... plus it usually has a stronger adhesive ... and should be the only type used on a vehicle.
Yes, you have to prep vinyl to use one-shot (unless it's a enamel receptive the paint will flake right off) I'm not sure what is used to prep it because I paint mine with vinly screenprint inks ... but I'm positive someone here knows.

I've had great results coating out the vinyl with either Frog Juice or One Shot UV Clear and then painting with One Shot. I did this on my own truck. It looked like new for 6 years, then I sold the truck. Just remember to NEVER clear again after painting. The clear willl try to reunite with itself, going thru the paint causing it to wrinkle up.

Mark got it. Calendered is actually extruded, and cast film starts in a 50 gallon drum, is pumped onto the casting paper at the head of the coating line and then spread to a 2 mil thickness by a teflon spreader bar. The gloss of the film is determined by the gloss of the casting paper. After it goes through the coating line oven, it's rewound off the casting paper onto a 1500 foot roll of clay paper face down, and then it goes through the adhesive line, rewound face up this time, and cut into masters from the original log. Masters are stored until they go through the slitters and then onto the rotary cutting units where they're cut into striping configurations and rewound into 50 or 150 foot rolls.
