Reading the previous threads to regrip a board, the options seem to be:
a) Intergrip or Sugar
b) Bote Cote epoxy or acrylic urethane clearcoat

Intergrip seems easy to buy at Whitworths.

What is a good product to use if I go for the acrylic urethane clearcoat option?

I've used Intergrip acrylic particles with Rustoluem Clear Satin spray paint, to good effect on many boards. Its not as hard wearing as Epoxy n sugar, but can be easily patched/replaced if necessary.

Is that acrylic urethane clearcoat?

2K matte clearcoat and intergrip? Thats as close to factory as you will get

If you're doing the whole board, not so worried about close level so intergrip over resin is fine- but use a non yellowing one of course

^^^ oops- gloss level.....

Thanks .. how about this one ...

^ I've only EVER used SATIN RUSTOLEUM.(Bunnings) It sticks to anything.
But I think the real trick is to NOT put too much on OVER the Intergrip particles..
I lay down a nice base coat on the board , about 1ft at a time. Sprinkle the particles as reqd. Then lightly spray over the particles as you start the base coat for the next section. Spray from a few angles. Just dont drown the particles.
Easy to see what you're doing n where you've been if under a fluorescent light. Set board up so you look at the light on an angle.
