Default Gelcoat Sanding

So after attending Uncle Hank's presentation at the convention I have been
inspired to sand out the crazing in my gel coat. I am planning on the
600-1000-1200-1500 wet sanding process and then buffing out the finish.

I understand the basics, but does anyone have a good primer on the process?

Thanks

ND gave a decent reply.

If hand sanding, start saying to yourself, "I must, I must, I must build up my bust....".
I like to say, "Sanding Gelcoat is like polishing granite with wet toilet paper".

Lot's of work.

A decent random orbital sander with disc's (going from 600 wet to 3000 wet) can make a HUGE difference. Using a block or spline board will work, but from my view, it's a LOT more work.
There's a reason a decent shop charges what they do, "they've been there, done that".

Final polish/wax also depends on the tools/wax you use.
So states the "polish guy" (job, not country..) on a number of projects.

[Someone in the shop today called me, "Buffy the dull slayer".... sorta fits.]
