. If the sealant doesn't adhere to the wood well, I don't see how using this prior to applying a "coating" is a good thing. Wouldn't a sealant generally be used to prepare a substrate for adhesion by another product (e.g. coating in this case). Since this sealant doesn't adhere I'm concerned any coating I apply is going to come off because the sealant hasn't "sealed" well.Henry 289 White Roof Sealant is a white, elastomeric acrylic patching compound specially formulated for repairing and preventing roof leaks prior to coating with an acrylic reflective coating

No prep, no primer, just put it right on the wood.
It dries into something similar to a sheet of rubber.
If you hit it with a hammer it would dent the wood, but the coating would flex with the dent.
Mine hasn't flaked or pealed.
The playapod is coated inside and out with it and is on it's 4th year.
I hose it out regularly.
Used it on this box cooler the same way.

The only thing is that the box could have been taller for more water reserve and room for a case of PBR!

Most of your pictures are gone for your Unicooler lid post. It looks like you used the same brackets to insert inside the box top, then I assume you put on some foam or something to complete the seal?
