Back after it again. We are knocking off what's left of the paint, and will remove the excess surface rust with white vinegar and plastic sheeting. Will neutralize this with TSP and water rinse. Then flip over and start cutting on the inside.

He graduated to the air sander. He was afraid of it 3 years ago. Lol

Starting fab on the inner trunk lip section. Theres more perforation on the outer skin lip once we opened it up. I think I am going to naval jelly this area and see how bad it is. May be worthy of just tack welding the holes up and applying a generous amount of epoxy primer over the clean pitted metal and leaving it alone.

I think we nailed it. Now I have to remove and or neutralize the corrosion on what's left before stitching this in, and making panels up for the outside.

Neil Young sang about rust never sleeping. This trunklid appears to have been sanded, and some rattle can ruddy brown primer put on it. Well that doesnt seal well at all. The process I am using to pull the surface rust out of the metal is simply 6% white cleaning vinegar and plastic to keep it wet. The rinse solution is trisodium phosphate powder mixed with tap water, a fine wire brush on the rusted parts and a green scotchbrite pad to scrub off the flash rust. The TSP and water act as a neutralizer to prevent flash rust.

The results of my first treatment from yesterday evening turned out great. In my last 3 pix I have applied the plastic and vinegar solution to draw more out. If you look closely you can see lots of spots of clean pitted steel. This works great on thin gage body steel that you dont want to hit with a sandblaster. This is a slow process, however the vinegar stops or severely slows down when it hits clean steel. When done we will spray coat it with an epoxy primer to prevent this from happening again.
