Yes, bulldog works great! You dont need primer unless you are going to fill scratches. If your mirrors are in good shape, you can clean them with the thinner. Tack cloth, bulldog, paint (color) clear.
I believe you want 2-3 coats of the bulldog.
A tip on spraying color and clear.
Do not try to get full coverage on the 1st coat! Meaning 1st coat can be dusted on. NOT A WET COAT! Also, paint all your edges first, then paint the rest of the mirror body. Give yourself 10-15 minutes in between coats. Enough for the paint to "flash off"
Your clear is what protects the paint. You dont need a ton of coats of paint! Once the mirror has full coverage, you are done with the color.
Usually 3 coats will do it. 1 dusting, 2 med wet coats.
I use 4-5 coats of clear.
Again, dust your first coat on. Dont try to burry the clear on the 1st 2 coats.

Do not paint in cold weather 70-80 deg is ideal
