Thanks TomW for the detailed process, I will apply it next time.
It looks like I was ok with avoiding contamination & cleaning with alcohol (no fish eyes) but neglecting the dropping temp and de-gassing of resin so always getting bubbles.

My entire process:
Clean shop, vacuum up everything. Preferably a day before.
I vacuum off the board last on that clean up day.
Don't turn on your vacuum cleaner the day you do the coat. Keep air still.
I put on vinyl gloves.
Wipe off board with tack rag, wipe off board with denatured alcohol ( dna). Use good lint-free paper toweling.
Tape rail. Wipe off with DNA, tack rag again.
Turn off heat in shop.
Mix and degas resin.
Pour on resin, using high quality brush, brush diagonally one way, then the other. Brush rails, brush longitudinally from center, finish with rails.
Get out of shop.
3 hrs later, remove tape from rail and turn on heat to 18c.
The principals are: dust free shop, no air movement, dropping temperature, no hand oils on board, tack rag removes dust stuck to board from static charge, no air bubbles in resin, don't over work brushing that can add bubbles.
Do you clean the brush for another use or do you use a new brush every time? Thanks!
Just followed all your suggestions Tom, brilliant finish obtained, which wont require much sanding. Thanks for the advice.
