How's life up on Montana?
Bet you're ready for some Spring weather?
Looking forward to hearing about your updates.
Ha! Spring is in full bore here and it sucks. Spring weather here is a 3-month tug-o-war between winter and summer. Right now we are in the muddy, slushy, slop stage but there will be several more foot+ snow dumps followed by more slop between now and June.
Slow goingI've been picking away at the passenger side quarter. Feels like a lot of work without much progress and it isn't as pretty as the driver's side. I started with filling pinholes. I don't know how other people do this, but I'm having good luck with placing a trouble light on the back side of the panel and then chasing stars with the welder.

I'm not sure why that is because the welder was set the same and I thought I was being just as careful to keep the heat down. Running over with the hammer and dolly cold got some of them out. I heated some of the worst areas and that helped a little. Unfortunately, my ancient JC Whitney hammer I was using had developed a little ridge on the edge that I hadn't noticed, and every time I whacked the panel, I put a nice little mark in it about as deep as the shrink I was trying to lose.

Click to view attachmentI honestly thought I'd just wind up chasing the problem across the panel, but to my surprise, it helped. I don't have a pic to prove it, so you'll just have to trust me. Now the question is, how much of that do I want to do?
Warp Nine CaptainYou may recall this side had the collision damage. Looked like probably a minor parking lot scrape that left two creases from the door jamb rearward that the PO's body shop had pulled out with a slide hammer and slapped on a 1/4 inch of bondo. Before welding the panel back on, I hammered out the creases as best I could, but did not fill the holes. Big mistake
In hindsight, I should have filled and ground the holes and then gotten the panel flat before putting back on the car.
The upshot is that I spent several hours chasing oil canning around the panel. I would shrink and/or hammer and dolly a bulge flat and lose the oil can, only to have it reappear after smoothing out another warble elsewhere on the panel. No doubt, this is my inexperience showing, and not understanding how to apply the "first in - last out" concept on this panel. But eventually, I was able to get it to where a guide coat and blocking is needed to straighten it more (same level of finish as the driver's side).
It's tempting to continue on and finish, but I think it makes more sense at the project level to move on to finish patchwork and rough grinding all the seams; then go over the entire car with a guide coat, blocking, and metal finishing. So, here's where I'm leaving it for now.

That makes me less enthusiastic about making every single weld line disappear. But at least it is going to have a LOT less filler than before. I swear I lightened that panel by 3 lbs. removing that filler.
There was one more task I finished up this morning. I needed to weld up the inside, bottom edge of the sail panel where it meets the trunk seal channel. Didn't take a before shot, but that went pretty well although I need to figure out how to get into the back side of that channel to get it smooth. Too tight for the angle grinder.

I had a clamp in there, but still didn't get it. You can also see some pitting left behind by moisture getting trapped under the thick bondo that was there. My thinking is that I'll address that with some body solder and will just address the weld seams the same way while I'm there.
