I think you're getting way ahead of yourself using 1200 after only 2 coats.



True.

He said "-WET SAND - start off using 600g and gradually move up to 800,1000,1200 after 2 coats"

I hope he meant move up a grade after each two coats, and did not mean doing 600, then 800, then 1000, then 1200 and then do another two coats.

Just to be clear - it should be:

2 coats
600
2 coats
800
2 coats
1000
2 coats
1200
