More sanding for 1/2 hour. The roof is hard.

Just physically hard, or is it difficult to try to maintain the slightly convex roof shape while sanding?

The latter. I put filler down, I sand for an hour, and I get bare metal spots and wavyness, so I try again. And again. I am getting closer, but it's a great rounded area, and let's not forget, a great rounded area which I welded on from another cab donor, and let's not forget, a great rounded area which I welded on from a cab donor after shaving drip rails, recontouring the front corners, and welding the rear cab seam.

The roof wasn't as discouraging as I recalled. I started by sanding everything fresh, doing a guide coat, and circling all of the trouble areas with a pencil. I think a lot of them were from debris in the spreader. I sanded my spreaders really well, and made sure the tear-offs were clean this time. Anyway here are the pictures which you clamor for. They are not very exciting, but I suppose that's a benefit.

Do your bodywork efforts have to shut down for the cold winter months or are you far enough south that it wont impact your progress?

I just invested in one of these, because I am not, in fact, far enough south that cold weather won't hamper my project progress, and I am, in fact, old enough that a frigid shop will make me cranky.

It means I will have to pick and choose when I can spray, and perhaps keep the paint products inside somehow. My garage is insulated, but not heated. I crack the door when I sand, and that can get chilly, but overall it's not bad. I have to decide today if I want to buy primer in anticipation of the weekend spraying, and if I do, I need to take care not to spray too early or late to avoid the cooler temperatures. Then again we will have nice 70 degree days all through the winter spread around. Today was in the thirties overnight.

Heat is on in my shop and will stay on until may.

Bottom line is if the car metal or primer contents cannot be kept at 65 degrees or higher as well as the shop temperature for the next 24 hours after spraying, DO NOT spray our epoxy as you may end up having to redo all your hard work.

Depending on how big your garage is, a couple of space heaters may be able to keep the temps above 65 during the evening.  It also depends how much power you have out there.  I just ordered an 8500W, 240VAC shop heater for my work space, which will get a 40 amp dedicated breaker.

I am not willing to take on the fire risk by running a space heater in my garage overnight.
