    Posted: 11 Jul 05 at 1:02pm
I've got a superspars mast on a RS600, the mast has significantly faded so I am considering varnishing it. This is not something I've done before (with Carbon) - does anyone have any suggestions as to what to use and where to get it from? Thanks.

i think most people just use ordinary yacht varnish after lightly sanding the mast. However i may be wrong. you can buy this from a chandlery or even a DIY store may have some.

Won't you just be adding weight just where you don't want it ?

I'd suggest you rub the whole thing down with fine wet and dry so that it is uniformly mat finish.  It will look just as good and be lighter.

But if not surely it has to be epoxy.

Firstly tape up the fittings you cant remove easily (gooseneck/ spreader bracket) and sail track. Then lighly sand with 400ish grit wet n dry (definatly used dry). Use 2 pack polyurethane varnish to give a hardwearing finish, and apply 2 coats whilst your at it. Definatly a job to do indoors if you can.

(Thats how I varnished my 800 mast anyway!)

Remember Epoxy is degraded by UV light.  If your mast is stored indoors, you dont actually need to do anything,  but if as I suspect you keep it outside and the protective layer over the structural laminate is degrading . . . . . :-(

Several coats of varnish or a coat of paint will provide UV protection (and look good :-)  ) Any decent brand of Spar Varnish is specially formulated for flexible substrates and high UV protection

Why not talk to Superspars themselves for advice? They must have seen this problem before.and know how to keep the additional weight to a minimum.

Thanks for the replys guys.

One other question which I doubt has an easy answer - I have non stlip stips (foam like grip) on the 600 which I want to replace. The problem is getting off the existing grip - is there any chemical or trick (possibly heat!) that can be used to get it off? trying to scrape it off is surprisingly slow work - I can't be the first person with this problem  cheers.

the chances are its pro-grip with a contact adhesive like evostik to hold it down, best way to get it off unfortunately is to scrape it, gently, seem to remember it working a little better when it was wet.  takes a while, use an old stanly knife blade , but scrape, do not try to cut the glue off.
