After applying the final coat (hotcoat/gelcoat), the board looks perfectly flat. After this i started sanding the board.
First grid 80 and then higher up to 280. After this i starteed to see bumps again. The bumbs are not really big but
still too big fot me. I want the board to look as nice as the boards in the shops.
Do you have some advice for me?
Can is just samd the coat imediately with sanding paper grid 400 and higher and then polish or am i doing something wrong.
I hope someone can give me the final advice to finish my board....
