No problem OP.
Hope you like the naan, GPW.
Only got about an hour and a half in tonight after stopping at ho-de-po for more supplies. Did a little detail sanding with 220 grit in the roof edge block, just to touch up those last repair areas, and where the roof and hatch spackle ran over the edges a little.
Then I went back to the curved long block and knocked down the top area of the hatch. The spackle has a little rubbery component to it (presumably the “exterior” element) so when sanded it tends to roll up into little snakes. You have to sweep or vacuum those away constantly to keep the paper working and not just rolling around on the snakes. Did the keeling over thing in both directions. Not sure if you can see the difference from the previous pic, but it is much closer to plan and is getting a little less flat.

But… we are not there yet.

Still looks like lumpy butt in a speedo. Canvas will definitely not change the shape of this.
In the beginning I said I was not a finish carpenter. Now I am telling you (again) that I am not a body man; but I am learning and hopefully improving.
I now know how Mel/atahoekid felt.
I don’t really mean to sound depressed or discouraged; just want to share all aspects of the building process. Standing on a step stool leaning out over a half tipped over camper and pushing a long board as far as you can reach, all while wearing a respirator, isn’t the most glorious thing, and I can see where I need to improve my technique (the warts), but I went at it with the spirit of a craftsman, so still felt good about how it is coming.
I need to find a suitable product to use as a guide coat. Spray paint is no good because it eats the foam, but I need a dark color to provide contrast with the white spackle and light blue foam. I wonder if that fabric dye I experimented with earlier would do the trick (more likely would soak in too far), or if some other water based paint would be thin enough to work. Any thoughts? GPW?
