Used System Three on my first boat and had problems with the wet out. Also had problems with clouding.

Now I use Raka and am very pleased. It does a fine job of wetting out. Especially if you use #606 very slow hardener. Just make sure the temp's above 60'F. Actually, I shouldn't be typing right now cause I've got some on my hands. Just coated the floor baords and did another lamination on my Walrus cockpit before turning on the computer.

That all said, Redfish Kayaks uses MAS. I haven't noticed any amber tinting on the light areas of the Redfish boats. Then again, I wasn't looking for it either.
