Started some work on the under body. The rear section of the car was a little rusty, from the rear seat forward the floor boards are perfect though. Kinda odd how the engine bay and rear floor area were the only sections that rusted. Anyway the engine bay is all new and now the rear pan under the seat, rear frame rails and underside of the trunk are like new.

If you don't remember this is what it looked like when I picked the car up:

Then I had the rear section of the underbody sandblasted. This is after the blasting and after I scrubbed it down thoroughly with soap and water and let it dry for 2 days in the 100 degree heat/sun:

After the sand blasting, cleaning and prep I used POR15 Gray to coat the rear underbody including the inside of every nook and cranny. I will also be painting the main floorboards but will be using a different type of paint (same color though) very close to e-coat gray.

hey Aaron......don't you miss the days of laying on your back on a hard concrete floor working on the bottom of a car??? :)

bottom of the car looks great. The stuff I used on the bottom of the 92 CHP car had a little more greenish/gray tint to it. You may already have some but the product was a PPG DP40LF and the catalyst number is DP402LF.

Looking GREAT, Aaron! That car will be stunning when you're done.

Lol, not at all the lift is the best tool I ever bought. I am actually thinking about getting another one.

I have some DuPont Chromobase that I had color matched to the ecoat. I did a friends 90 GT underbody with it and its what I plan to use on the floor boards. The POR15 Gray is pretty close and once it gets exposed to UV light it seems to tint more to the green/gray of ecoat.

Here is a pic of the DuPont paint I used to do the complete underbody of the 90GT, the gloss is not correct but it's what the owner wanted.

ohhh yeh I like that.... Do you think some sort of flattening agent would take away some of that gloss? That color is spot on !

I have seen clear flattening additives but never used them. I know DuPont has a line of semi-gloss and flat clear coats. I think the flat would probably be the way to go for a 100% correct resto. That 90GT underbody was straight auto clearcoat Nason 496-00 it’s a lot glossier then the picture makes it seem, but like I said that’s what the owner wanted. The POR15 I sprayed came out as a semi-gloss, it’s probably a little to shiny to be OEM but I wanted a really good coating on that rear section of the car. I am going to use a semi-gloss clear on the floor pans so it matches the rear section of the under body.

You're going to have quite a pair of SSPs when this one is done. Very nice.

Hey Aaron if you don't mind can you send me the part #s for the stuff? I will try some of that on the bottom of the 85 Texas car.

Jim, are you looking for the DuPont stuff or POR15? Here is the POR15, I will have to look up the DuPont stuff when I get home.

OK, so now that the fire is going again under my butt I have some more slight progress to share. A couple weeks ago my buddy Brandon who is an amazing welder and metal fabricator helped me replace the last pieces of the body that had rust on them. The only thing we have left to do is the front section of the floor boards.

Here is the lower section of the left rear quarter panel. It had no rust on the outside but some rust on the inside, I figured I am this far I want to get the car to no rust anywhere at all. This is another donor panel from Ron’s ISP 4057 SSP.

This is how the right hand wheel arch came out, I had to get this from a donor car in the junk yard. I cut all the patches and Brandon did the welding, grinding, fitting, it’s like it was never done, I have not blocked it yet but it does not feel like it will even need a skim coat. Like I said he is amazing with metal!
