wire wheel it, use POR15 over the rust scale, spread filler on it and sand before primer and splatter paint (will hide alot of imperfections)
The filler is an interesting idea. I probly won't use POR15 because I already have a gallon of epoxy and I'm not a fan of the POR15 system. The real issue I'm having is figuring out how to wire wheel everything in the trunk compartment. There's areas I know I won't be able to reach with the equipment I have, and the rust in some of those areas is bad enough that it needs to go. So what did some of you do to reach areas near the base of.the quarter panels, around the lid latch, up onto the wheel wells, etc??
Here are some photos of my trunk area I took today. Overall it is in good condition. The problem areas are where the drivers side wheel well meets the trunk pan, and on the inside of the quarter panels where the bumper wraps around. Any advice on how to tackle these issues would be greatly appreciated.
The 3rd photo is the rear corner of the quarter panel that has a lot of rust, and a small slit that I can see through. The 4th photo is where the bottom of the drivers quarter panel meets the trunk. The 5th photo is where the drivers wheel well meets the trunk pan.
did some more grinding after posting those. Looks like the seam where the trunk pan meets the wheel well on the drivers side (photo 1) is rusted all the way through, but it doesn't go very far, maybe only an inch or so into the trunk pan. The rear corners of the quarter panels (pictures 2 and 4) look to be rusted through in places, with bondo stuck in there. I ground out what I could, but I didn't want to blow through the metal until I knew what I was going to do to fix it.
thats the good thing about POR15 you do not have to get all the rust off just the scale and it is supposed to make it inert, the epoxy won't do that. Your best bet will be soda blasting and patching the metal if its rusted through the wheel house. The pitting on the pan can be epoxied, filled with body icing and sanded smooth (tedious), then splatter painted.
I guess my next step is to strip the quarter panels to see what kinds of secrets they're hiding before I tackle the rest of the trunk. I have some rust converter paint that I used on my floor pan. It works really well. I will most likely do the same in the trunk, then epoxy. Still haven't figured out what I'm gonna do about the areas I can't get to with the wire wheel.
Took a slight detour today from the GTO and decided to get some bodywork practice on my motorcycle tank before I get to anything too serious. Sanded it down to metal, got all that old mud out of the dents, put down some new mud, feathered it out real well, primed it, sanded it, and shot it with flat olive green paint. Then I hit the gas cap with plasti dip, which looked good but I don't think it is durable enough. I will probly peel it off and powder coat it instead. My plan is to put my rebuilt starter, New chain and sprockets in, reattach the newly painted tank, clean everything else up, and sell it so I can get more parts for the GTO. Roommate sold it to me for dirt cheap so I think I can turn a good profit. After that I removed the drivers side door on the car, took all the hardware off, and stripped the paint off the door shell. Has some rust at the bottom front corner but should be an easy patch. Forgot to take pics of that so I will post more later. Slowly but surely all that old paint is coming off to reveal a remarkably solid 43 year old body, especially for the Midwest.
I decided to pull my front and back windshields this week. Turned out to be a good thing. There's lots of cleaning up under there that needs to happen. I've been grinding all of the surface rust and paint out of the windshield channels and there are a few areas that are rusted through. However, they were hidden under bondo so my guess is the previous owner saw the rust and smacked a little mud over the holes. It seemed to have worked, as the rust doesn't appear to be any worse than when they mudded over it. What's your suggestions for how I should approach this? Mud it back up, or try and cut it out and weld new metal in? My welding skills and equipment are primitive at best... The holes aren't bad, a few dime sized or smaller with one area about two inches long that's swiss cheese. I'm thinking if I sealed everything in epoxy and put new mud in it would be perfectly fine but I just wanted to ask. I'm sure its a common rust problem.
Those small areas i would cut and weld in patches now while you have it apart. Take out as little as you have to to get to good metal and practice your welding skills in those hidden areas for the rest of the body. Like my buddy says, i am a shitty welder but one HELL of a good grinder.
