How dry for glass/epoxy bonding

[JohnC]

I have a stripped hull that has been sitting outside in the rain for a while. Since Dorian passed us by we have had our first string of dry days in the last month or two. I just cleaned it up with a hose and scrub brush two days ago and after a day in the sun it looked clean and dry. I put a tarp over it to keep it that way and I'm hoping to start adding parts back in soon.
I don't know if there is a benchmark moisture content that I need to get to before laminating. I don't have a moisture meter but I was considering getting one if needed, I saw one for $45 on Amazon.
Can someone advise me on how dry this has to be? Is there a moisture content I need to get to for good bonding? Do I need to buy a meter? Thanks for any advice.
