Sorry Mark - mean't to say Mark, not Mike. I noticed the Epic website mentioned post-curing at elevated temperatures. I'm still not sure how important this is. The guys who build the strip boats usually elevate temperatures temporarily in musty basements or mid-winter workshops - but that's just to finish off curing.
