Hi Alkay, never used Feast Watson so cannot comment. Reckon that most top coat finishes if thick enough would benefit from super fine wet sanding to take out any small lumps and bumps if nothing else.

Never heard of a cross hatched sanding method as it is almost taboo to sand across the grain on anything as you run the risk of introducing scratches.

Ok thanks waz I might do a test run.
Here is the advice I got:

...the way to get a glass flat surface is to sand in a cross hatched way, so thats basically just one stroke at a time, you glue your sand paper to a longish flat peice of timber, something like chipboard, in this case maybe 25cm by 10cm. Then you take just one stroke from top to bottom at a 45degree angle, top left to bottom right...then the opposite, and the last stroke is just straight top to bottom at no angle, then you repeat that entire process until you can put a steel rule all over the surface in all directions and get no light between the timber and the steel rule, then as you coat up, you go back and keep on repeating that sanding*process with every coat
