undercoat

I've been sick for the last 4 days with the flu. I mean come on, who gets the flu in April?! The Import Alliance Atlanta show is in 14 days. I have an exhaust to somehow TIG weld on, wiring to clean up, battery to mount, seats/lights/fenders/bumper to install, and an intake gasket to replace. And still have to go for a shake down ride. What have I been doing? 

Watching a Fast and the Furious marathon. I picked up a bootlegged copy of Fast 5 in Malaysia and to my dismay it did not work in my mac. My blue-ray player, however, was not as picky.

In an attempt to be somewhat more productive, on top of loading up on cold med's and reciting F/F quotes, I'm also catching up on blogging.


The inside looks pretty calm before the wiring storm. And yes, that's a o.5o cal ammo case. It still has dirt on it from the desert.



There's a KK in my engine bay!



There were a few spots in the engine bay that needed to be sanded and painted over. These KK sanded by hand and clear coated over.

Another big reason for taking out the engine yet again was the undercoating. While I was under the car playing with the transmission mounts way too late one night, I realized that something was coming off on my elbow making me much more dirty than planned.

Sections of the undercoating, as it turned out, a few square feet around the transmission tunnel, was not really undercoating. I mean it was coating under the car, but it was not painted on. It was a grease mixture that covered the bare metal. At fist I was stressed out but a little digging revealed it was just that, sealed before paint as it seemed. Maybe the previous owner needed to cover it to prevent it from rusting before paint? To confirm, the brown color in the pictures is a paint, not rust. Either way, I wanted to take it off and coat it correctly and needed to remove the transmission to be proper.






I scraped a bit of the real undercoating off during one of the engine and transmission installations and also wanted to touch up this. Most of this was on the passenger side of the tunnel, as viewed on the left side facing rearward. The right side is where it gets interesting though. At first glance it looks pretty good, normal undercoating and all.



But then it rubs right off to the touch.





Add a paint scraper into the mix and it really comes off. Like I said, it doesn't look to be a simple cover up, and KK took the grease mixture completely off, until she hit real undercoating on all sides.













Condition of the shell, as usual, looks great. No rust. I was originally going to simply spray some clear coat over the areas that needed it, but after further evaluation I thought it best to get some real undercoating. It was a larger area than I first thought, and it was under the car and needed to be sealed properly.

I took my 28o z to a truck shop and had rhino lining sprayed on professionally several years ago. It held up pretty well but started to peal at the edges and was very difficult to clean because it came out very rough. Being in the engine bay, you would cut and scrap your knuckles and fingers just looking at the engine, let alone actually working on it for any length of time. I won't do that again.






The underside didn't have the same limitations, but I still wanted a smoother undercoating that would last and protect. I found some at home depot that did the trick quite nicely. After picking up some supplies, we hand rolled on the new coating. Some of these shots are after only one coat. If you put it on too thick it wouldn't stick, so KK applied it in several layers over several days as I attended to other parts of the car and engine.

Time will tell, but it shouldn't have the same edge peeling issue as in the engine bay as there is no physical edge to the panel that was painted. KK blended it into the undercoating that was already on the car. It also came out much smoother than the sprayed on rhino lining that I was used to which was exactly what I was hoping for. It matched perfectly with the undercoating that was already under the rest of the floor pans of the car.
