Gunsmithing Replacing gel coat on a mcmillan stock

[Jason Shore]

What do you guys do when you sand below the gel coat on a mcmillan (fibreglass) stock. Do you need to re-seal it or will it be fine left as is ?
Had to sand the bottom metal inlet
Any replys appreciated
Thanks Jason

I too would like to know how to gel coat a sanded area on a MCM.

Gel coat cannot be replaced in any manner that duplicates its original application. It can, however, be repaired using automotive glazing putty, which is a final step product used to fill imperfections left from applying automotive body filler. It allows final sanding to achieve a smoother finish. Using a flexible vinyl spreader, a thin coat can be overlayed, than sanded smooth once it cures. Block sanding is often the better technique. The glazing putty still requires priming in order to receive paint effectively.

Color gel coat camo must color matched and repainted.

Contact McMillan.

They can put you together a small "Patch Kit" that matches the color pigments in your stock. It is an epoxy type mix that you mix, place and after curing, buff. Potentially you could have it look almost like new.

Maybe PM Ryan.

If your not building it back up all you need is the pigment color. Thats what McMillan does when they cut out for the bolt handle and ejection port.

It's very easy anyone thats had a fiberglass boat for any time has needed chip repairs done.Kits like these are butt simple, just prep the area mix colors to your desire apply and shape. Cover with the texture paper of your choosing then let it set up.When its done you can final sand or buff to your content.

Re: Replacing gel coat on a mcmillan stock

Thanks for the replys guys. I Dont care much about the looks of it i am more concern if the fibreglass needs to be sealed to prevent moisture getting into the fibres.
I dont know how bare fibreglass reacts to moisture .Will it expand etc ?

You need to seal it some way even if you just paint it.

Few spots on my return stock were gone over with some sort of yellowish clear "plastic". Don't have it around right now to take a pic but who knows what it was.

My gunsmith (Jon Beanland) has fixed some small spots on my McMillan's with a patch kit from Mcmillan. They look great. You wouldnt know they were there unless you knew where to look. He is very good though!! I dont think i could do it myself. Lee
