I used POR 15, then POR Etch Primer, then followed up with POR Hardnose Light Yellow. It is pretty close to the Corvette Yellow I plan on painting my truck. I used this same process on the underside of each fender, and inner fenders. If you do use the Hardnose, it doesn't spray well, I kept it to where I could brush it on, out of most eye sight. Yeah, if someone sticks their head in my fender they might notice a few brush marks. Good luck.
