I'm not sure, I don't know much about this, I'm just learning as I go. However, I tried sanding one area with the DA with 60 grit for quite a while and the cracks didn't go away until I got down to "blcak". The boat is blue metalflake, but under that is a flat black material (I assumed gel coat). From what I have been reading, it looks like they spray the flake in the mold (mixed with clear gel) than spray a dark colored gel over that before laying up the boat. So if that's right, the clear gel coat with the flake is fried out and cracked and the black under neath is smooth.
That being said, it takes so long to sand down to the black gel, I don't think I have the patience to sand all the clear and flake off.
