65 SC Resurrection starting.

Slow day cleaning the shop up for the paint stripping. Kept smelling that bad gas smell, from the carburetor cleaning. Traced it outside to the old tank. Decided to open it up and look inside. Boy was that a bad idea, I may never get the stink out. The loose rust and scale is from the top of the tank. Just like before when we split a tank to test electrolysis rust removable. The top surface has most of the rust you see in the fuel filters. The tar from gas remnants tooled like undercoating.
I have never seen a tank this bad..

the black tar in the below left photo, was still pliable and damp. That is the stink


this photo shows the clearance at the top of the tank and the internal slosh baffle. So when cleaning one with Evaporust or molasses, do the upper surface first. You can see a little clearance between the baffle and top. The ends and finally the bottom surface. Same process when using POR-15 or some other tank sealant. The baffle is almost solid at the bottom, but open at the top. So put the sealer in the top surface first, so it can get into the bottom half.

Another fun day today, thanks for looking

Is this tank really savable underneath all of that? That laser sure would be nice right about now.

Floors….my least favorite part of these cars. The jute came off with some heat and a wide scraper, but the rest of the floor was a little different. Knotted wire brush was polishing, not removing the undercoat. Bob had a great idea oscillating saw or multi tool with a scraper and a 1” blade with dull teeth it got under and chipped off the old tar and paint, like a needle scaler on a weld. It worked super, easiest floor we have done. Lots of hidden surface rust under areas that looked solid and intact. But no holes or swiss cheese in the low spots. Next is the knotted brush, scotch bright surface conditioning pad, then Ospho (Orthophosphoric acid), 3M 8307 self leveling seam sealer, epoxy primer then Raptor truck bed liner.



I know some people will not like the idea of Raptor, but it looks like factory undercoating, tuff seeps in to any cracks and will permanently seal the floor. It’s also will strengthen the floor and reduce road noise. Goes on like shatz but much harder but urethane based and flexible.

Again, that laser they confiscated from you sure would have made this clean up go a lot quicker. What's going on with that BTW? The floors in this car look solid.
