Just started on my first panel. It seems to be going Ok but just wanted a sanity check. This panel has 2 coats of filler. I still have a few low spots. As you can see it has some curve to it and it is loaded with lots of small dings. I am using the small 3M block with the nails in it.
My questions are:
1) Should I be using a longer sanding block and should it be a flexible block?
2) If I discover a high spot, can I just tap that down or will it cause a problem since I have already put filler around it?
3) some of the high areas expose the bare metal after sanding, I assume that is not a problem as long as they are not sticking up.
4) How perfect does it have to be before I go to the next step (High build primer)? I have not used a guide coat yet, right now just going by feel. I plan to use a guide coat to check it before I spray the high build primer.
Any other comments would be appreciated.
