Phosphoric acid is the the blueish stuff. You have to neutralize any acid you put on before you are top coating with primer.
JS. The rust here is more manageable than back east because the lack of humidity. A piece of bare steel can sit outside for years and not rust away to nothing.

My door has been stripped bare for a few weeks now. Nothing on it to stop rust and no sign of it either! I guess the dry weather has some advantages!

Yup
Back in NY when I welded any patch panels or new sheet metal on the welds had rust the next day just from going hot to cold and the humidity.

Well, it's been a while since I updated this thread, so here goes.

I took a break from doing body work to work on the engine. I figure I need to know how much roll bar/cage to put in. Hopefully just the minimal amount. Then I can get back at body work. I'm almost ready to start machining the block. I have it, and the crank all prepped, and ready for machining. I bought POR15 in silver to base coat the engine with, and I got some of POR15's Pontiac blue metallic engine enamel. The engine should look really amazing when done. POR15's engine enamel is awesome, and tough. Engine will look like it was powder coated. I've been doing a lot of port work on a junk 670 head to figure out what I will need to do to the actual heads I will use.

Hope you don't want to put a back seat in the car. Also would like to put a good ARB out back.

ARB = anti roll bar
Make the car launch nice and straight.

Worked on some body work for a couple hours today. Trying to remove this pesky dent.



So I heated it, and quenched it with ice cold water. That helped some, but still the dent was there. So I hit it from the inside, and it oil-canned out. Now, it is a bulge that I cannot get rid of.







I hit it, and it expands out, then I quench it, and it shrinks back to where it was. I tried heating the area around the dent and quenching it, but that didn't help either. I'm at a point where I'm not sure what to do. If I dent it back in, and use body filler, I'm afraid it will oil-can out someday, and pop the filler out.

If I leave it slightly bulged out, and use filler in the low areas around it, I'm afraid even though it will be smooth, and nice, it will have a bulged appearance on my door that just won't look right.

Any suggestions?

Need to shrink it more. Try smaller quarter size spots than one larger area. It should be nice and tight when done correctly.
If you need a hand let me know.

Started working on that pesky dent again yesterday, and today. Fellow PY board member Louis P. sent me his shrinking disk to use to work this bulge out. Well, I'm happy to say that after a couple hours of patience and working it, I got the bulge almost all the way out. Probably another hour or so, and I'll have it done. I'm real happy with how it's turning out. Hard to believe that rubbing a stainless steel disk on the metal will shrink it, but it does, a few thousandth's at a time. This bulge stuck out about a 1/2". Now I can barely feel it with my hand, and looking at it from the side, i can barely see a slight bulge still. I bought a slapping spoon and used that to work the low spots around the bulge out, so now it feels pretty smooth, and will need very little filler, if any. We'll see how the rest of the bulge comes out. Here are some pics.

Here is what it looked like when I started.





After working it some.





Getting there.
