From left-long board sander, 1/4 sheet sander, flexable sanding block, dolly, pick and bump hammer, and my big rasp.
So I started by knocking out the dents and raising the low spots with the hammer and dolly. I raised the large dents with a 5lb sledge hammer wrapped in a towel, and took care of the smaller stuff with the small hammer. I was initially using an old ball peen hammer, but then the scratched face of the hammer was transferring the scratches to the roof skin. So I bought the hammer and dolly, and they do a good job, with practice. Once I flattened the roof skin to the best of my ability, I started on with the filler. I first used Bondo brand filler:
Here you can see 2 brands of filler that I tried; Bondo (grey) on the right, and then Royal Pro (white).
I found the Bondo easy to mix, and nice to spread. It didn't sand too easy, and when cleaning it up afterwards I found that it soaked up water easily. The Royal pro filler mixed well, and it also seemed more waterproof than the Bondo. It was harder to sand though, but left a smooth surface.
I lucked out and found some Evercoat Rage Gold at Hymus auto parts (where I buy a lot of my bodywork supplies). I have read that this is the preferred filler for a lot of people, and it seemed to work well for me. It mixes nice, sands easily and seems reasonably waterproof. I think that I will use this for the rest of the job, and hopefully the top coat of paint will not show the different fillers that I have used here.
So, filling and sanding continues. I've already used POR 15 in the rain gutters to keep them sealed and rust-free, so I just need to complete the filler and then maybe prime the roof before I continue with the rest of the body.
