: I am building a yost sea rider and I bonded the keel to the cross sections 2
: days ago and the epoxy is still like gum.I mixed West System 105 resin,206
: hardener and 403 adhesive filler. The 105-5 parts and the 206-1 part
: without a pump but with a mixing cup. Then added the 403 to thicken. The
: epoxy is like a some what hard gum,but not sticky. Did I mix to much 403
: into the mixture? I think I will have to cut the keel of and redo it. kirk

One of two things either the ratio wasn't correct or you didn't get it completely mixed.

Should be able to soften the epoxy with a heat gun so the keel can be removed though without having to cut it off.
