I'm still learning which materials work best for me. I used a different product for two boards that was " coating resin" from easycomposites in UK. . There is amine blush buts it's easy to wash off with soap and warm water and scrub sponge. Polished out nice. ( orange board). Then I made a board with the RR and additive F. Lamination was easier. It flows out better than EL 2 from Ez. But gloss coat ended up looking like resin had 0,5 mm crystals on the surface after polishing. I could not figure it out. It was smooth, but it had these weird crystal effect. I wondered if it was a reaction with the Polish compound, or the Additive F caused it. The bottom I sanded to 800 and turned out flawless. ( white board.) you can see crystal effect over black logo.
So my next series of boards I am using the the Ez EL2 and a new coating epoxy they have that's supposed to be better than last year's. I'll use up the RR on some SUP or other project for myself.
RR was like 50% more expensive too..
I'm working in temp controlled shop. clean and working carefully and methodically. Taking lab notes.
Tricks I read about, and use successfully for final gloss coat. Clean up board, blow off and wipe with dna, tape off rail as needed.
Blow off board W compressed air. Wipe with Denatured alcohol ( dna)
Blow off. Wipe again, blow off. Do not touch with bare hands.
Use small emount epoxy ( 60 gr for 5-0 board) and scrape it on then all off board into cup to dump it. Then pour on gloss coat, brush out diagonally x2, lengthwise. Let sit 3-4 min. Hit with hot air gun on low about 20 cm from board, sweep it along, don't stop. Small air bubbles rise to surface and pop, Resin flows more. Wait 5 min, repeat air gun, wait 5 min, repeat airgun if needed.
If you get any fish eye, you can rub it with clean gloved finger add a dot of epoxy and air gun it.
