number one get drunk so you don't have any idea what your doing, oh ya best to have the car ready to go before that. then attack it with no purpose. keep in mind that it wrinkles by film thickness. so if you lay it down in a pattern as you would normal paint it will wrinkle more on the overlap. my first attempt on Jim's 66 came out looking like a checkerboard.
so open up the gun as wide as you can used as little of reducer as possible and go in circles every which way and don't be afraid to get a lot on.
if you step in the garage latter in the day and it has not wrinkled, don't get discouraged. park it out in the sun and as the rays hit it it will wrinkle.
it had not wrinkled on that 73 over night. I ran it outside the next day figuring on having to remove the paint and even though it was cold that morning as the sun hit it you could watch it wrinkle. kind of weird stuff.
