Matt, I have done exactly the same thing with my console. I didn't have any mould release wax so just used plenty of good quality car wax - worked fine
Trouble is, in my normal fashion I decided it needed to be good and strong, so I used rather too many layers of 600gm csm. Surprising how heavy it can get
Oh, and the console was off the boat, so that the surface I was working from was as horizontal as possible.
So I have been trying to decide whether to use it, and for quite some time now I have been running with a soft backed cushion attached to the console with heavy duty velcro. No problems to date
