I like to use the Upol filler primer. It comes in a beige color that makes it a LOT easier to see the imperfections that need to be blocked out. Also, how much you will need is going to depend on your experience/skill level. I take the car to bare metal and fix all the obvious areas first. Then I lay down a really thick coat of primer over the entire car. The idea is to block the car with a long board until the entire car is flat and smooth. If you break through the primer, then you will have to go back and address your highs and lows in all of those "break through" areas. then another coat of primer for the final blocking. And if you break through again, then you get to repeat. If its your first time, don't be surprised if you have to block the car 3 or four times and go through a couple gallons of primer. And I don't recommend the aresol aircraft stripper, because it eats through glass, wires, chrome, everything. You have more control over where it goes if you use a brush. Take your time and make sure you do this right the first time. Because after its painted, if its not right. Then you will either have to live with it, or start over from scratch.

 

Is the U-Pol a Urethane 2k primer? It's always best to use epoxy over bare metal and then spray 2k over that for blocking.

What kind of aircraft remover are you using that eats through glass!?

 

Here is the Urethane 2K primer I use, http://www.amazon.com/U-POL-URETHANE.../dp/B002MCTAT6. And I cant remember the brand of aircraft stripper I use, I need to go get some anyway. So I will let you know what it is. But YES, its etches glass LOL.
