When I replaced the progrip on my 29er recently, I found that good ld white spirit took th glue off fairly well.

Scrape it off and then rub the area with acetone prior to fitting the replacement.  Try to use less aggressive liquids than petrol, try turps substitute or paint thinner first?

Grass fiber. I havent tried petrol - I also havent used a sharp blade to cut it off as opposed to scrape it off - will give it a try and let you know!

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.

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.

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.

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!)
