Are there any thoughts on this (other than that the stuff isn't very satisfactory!). I've kinda acquired a barely started ESB4 kit which has got one of those fingerboards, and its quite obvious that the stuff is picking up every little bit of fluff going, and really badly needs sealing, unconventional though it might be.

My background is boat building rather than guitars, and I have some very low viscosity epoxy sealing primer, and I was wondering whether it might be worth using that to seal the surface and consolidate the loose fibres. Is there any experience with that sort of concept?
