12/3/24: Now that thanksgiving is over, I got back to doing the bodywork on the back of the cab. Over the last three days, I finished the bodywork and sprayed three coats of urethane primer. Aside from the usual, apply Bondo, sand it off, tap down the high spots bring up the lows, apply more bondo and do the same a few more times, feather, etc. etc., I ran into two issues.

The first was the joint at the belt line. When I was sanding , I started to see a bit of rust poking thru. I decided to sand as much as I could then seal it in with JB Weld. I used my finger with a glove to squeeze it in the joint, then allowed it to dry before smoothing it out. I used a propane heater aimed at the back of the cab to warm things up a bit in addition to the kerosene heater I normally use to help the epoxy and primer to cure. I bought 6 minute epoxy (setting time), but it still took about 6 hours to fully cure.

The second issue was my Husky HVLP gun refused to cooperate and I couldn’t get any volume to come out of the gun. It acted like the primer wasn’t thin enough. After several attempts, I bought out my better gun, an Eastman Contours II and changed the tip to a 1.7, and that worked much better. I’ve never sprayed 2K urethane primer before and I’m thinking the tip on the HUSKY might be too small. It’s not marked and I have no clue how to measure it. Once I got going, the primer went on a bit bumpy like it was sprayed too dry, but leveled out nicely.

The cab is ready to be blocked out this spring. On to the doors!
