Looking good.
Keep the sanding in as straight a line as possible, then when you move to the next grade sand at 90 degrees to the lines on the cover, then go 90 degrees again etc.
What this does is remove the last lot of lines made by the wet & dry, because it is done at 90 degrees it doesn't open the groves but flattens them down, sounds a bit crazy but it works
Remember
400
1200
2000
Then polish
