Good news. It's dry and solid as a rock!
I guess it is down to the last coat before I can get it in the water.
There are still some minor dips that I obviously didn't take enough care of before putting on the carbon. But I am probably going to let them be, as they are only on top of the board and hence of cosmetic relevance.
I haven't decided which layer to do first. The very thin epoxy layer on the bottom or the final coat on top. I am worried some dripping might occur and those drips will become solid and I will have to deal with them. :-/
Currently I tend to do the top first, and then sand off any drips and put the final very light coating last on the bottom.
Does that make sense?
Thanks again for all the help!
