Default Underbody Painting

Guys,

Amanda and I are doing final detailed cleaning on the underside of the car today in preparation for painting. Here is our plan, please advise if I am doing a step wrong as I want this to hold up and not get caught with any "Oh Sh%t's"

1. Finish clean up to bare metal (all bare metal will be gone over with 50 grit paper to rough it up)
2. Wipe entire underside with water using 3M scourring pads
3. Wipe entire underside with Phosphric acid (let site about 10 minutes keeping area wet to help remove any microscopic rust)
4. Wipe down with water again using 3M pads
5. Wipe down with PPG DX30 wax/degreaser
6. Spray two coats of Omni AU MP176 Etch Primer (PPG Product) Mix a 3 to 1 ratio of MP176 primer to primer catalyst MP177
7. Spray one coat of PPG DP90 Mix 2 to 1 primer and catalyst
8. Seam seal all seams using 3M Ultra Pro seam sealer
9. Spray two coats of PPG DP90 (this is going to be the final topcoat as Amanda likes the color and the paint store said it would be fine as a top coat, true?)
10. Have a bunch of beers and give each other high five's (Beer is only for me )


How does this sound to everyone? We hope to finish clean up today and paint first thing tomorrow. I was going to originally spray Eastwood products but they will no longer ship HazMat to Alaska, so I am screwed there. Luckly I have a couple PPG paint stores here.

Thanks,

Bill
