Looks like your resin was setting up as you rolled it on.

I've been surprised by this "sticky resin" problem one time or two, when I just used
some resin out of the mixing cup to touch up something else, lost track of time,
and then realized I was supposed to be pouring this batch in the roller pan and noticed
it was very sticky.

This is why I never mix more than a 6 oz. batch. And don't pick up the phone, or get distracted.

How large a batch of resin and hardener did you mix up and how long did it sit in the
mixing cup before you poured it in the roller pan?

I use System Three regular resin most of the time. I'm just trying some MAS and
the set-up times are dramatically different. Six to eight hours to tack free at 85˚
for slow hardener with System Three. Two to Three hours to tack free with slow
hardener and MAS at 80˚.

I don't know what kind of time you could expect with West's slow hardener at 80˚.

If you heated your shop to 80˚ for six hours you didn't need to heat anything else,
if your resin and boat are in the shop.

If you had a large batch of resin that was heated over 80˚ poured in a pan heated over 80˚
this could account for your faster than expected set-up of "sticky" resin.

Your resin should be watery thin for a good wet-out.
