What would be the point of using it? What are you trying to achieve?
It is a holding primer for applying to blasted steel or as a tie coat. Quite thin film so you would need a lot of coats to have any real osmosis protection. High VOC so definitely not suitable for osmosis treatment.
Really needs to be overcoated with another epoxy.
Before you use it the surface should be well abraded and it would need to be well abraded itself before putting anything else over it.
Personally I would't bother on GRP. Sell it to someone with a steel boat and who is having it blasted!

Pasarell has said it all.

You cannot find anything about using it on GRP because it is not intended for use on GRP.
