the change of weight will down the difference in weight of the pigment to the resen/hardner it replaces it think, overall i'd have thought that it would be pritty small.

A decent varnish should protect from UV as well as paint will I think... but there is an argument for using a light coloured (white) paint to reflect heat. Not sure on the weight front but I doubt theres a lot in it.

Why would applying 2 pot coloured paint weigh more than the equivalent volume of 2 pot varnish?

Does the varnish absorb the UV or reflect it? and if so shouldn't the paint absorb or reflect it better?

i had that with my rs300 topmast. however the bottom mast was fine. Turns out, 2sails after i bought it the bottom section went. either way, i would throw some varnish in its direction. atleast then if you need to send pics in to the insurance company if it goes then it looks well cared for

If bits of carbon are coming off when you rub it with a cloth that sounds like a bit of a problem! Are you sure its not just the laquer rubbing off? I'd take Jims advice and just re-varnish it as then it'll at least look good even if it is proper rogered!

Unless its really peeling I'd just use two pot. I doubt putting more epoxy on would help: it would be a kinda desperate measures option.

my mast on my 600 needs some attention, its currently in the garage. when i rub it down with a cloth lots of hairy little bits of carbon come off. what should i do? will putting some new varnish on it be okay? (i have some twopack varnish from when my dad was using it for something) or does it need more drastic measures?

Did you use the wax or the aresole(sp?)?
