To seal the ceacks, consider using the seal stuff for doors and window ac units. Looks like you are off to a great start. The warping from humidity may not be an issue if that wood is sealed from the manu. I use to work for a company in shelby, ohio and we made things that looked a lot like those. We sealed them to so you never know ehh?? Mylar or paint.... hard decision, personally i would paint it, wally world has spray paint that is very reflective but mylar is mylar and works good. Good luck, and now I am reconsidering my DWC Cooler I created....
