What's the best holesaw for GRP (acrylic bath and GRP header tank)?

I'm building up a set of the Bosch holesaws but I'm worried they may
either chip GRP or the GRP will destroy the saw teeth. Are they OK or
would a grit edged one be better, eg:

I used an ordinary (bi metal) one to cut holes in the grp bumper on my old
Rover for reverse sensors and it gave a perfect hole. I'd say it would be
ok on acrylic too - but keep the speed very low to avoid melting it.
Perhaps lubricate with water.
