How big a problem will I have with epoxy (Mas I think, it is part of a CLC kit) which I have left in the bottles with the pumps on for about 6 months?

I lost heart in the build and then the winter came. They are still in the original bottles and have been in an unheated garage in Los Angeles. I think I started using them in June or July.

I suppose it would be a good idea to do a test panel? I have not even tried to see if they are in working order.

I have cleared a lot more room around my building table which was a nightmare in the first portion of my attempt at building.

If I have to do the dreaded and buy new epoxy, can I use any brand I choose over what I have already done--the inside surfaces of all the panels.
thanks for your opinions.

Hope to have a boat by the summer.
