Dale,

I've seen end-poors on a couple S&G's that shrank considerably. I poored mine in stages, but still saw measurable (if minor) shrinkage. Casting resin does exactly the same thing, so I assume it's the nature of resins to behave this way. Perhaps this stressed the cloth enough to cause your dots.

: Today I put some scraps of carpet in the bottom of a bucket, filled the
: bucket with warm water, stood my kayak on it's end inside the bucket of
: water and did the end pours. I noticed that the cloth on the outside along
: the seam and even in the cloth on the hull has a bunch of these dots in a
: small area now that the end pours are done. When the end pours fully cure
: I'll just sand it off and lay up some new cloth so it's not really a
: problem. What I'm trying to figure out is where the compression load came
: from. Is it just the fact that the kayak was on it's end? That's all I can
: think of how it would have happened. This happened to a real small amount
: on my triple also.

: I would think that if the heat of the end pour curing expanded it would put
: the cloth in tension and would not cause this problem. Any ideas?
