Good point. I doubt there is any seam sealer. I bet I could just close off the entire cowl. Not going to use it for anything other than windshield wiper arms.

I plan on going through the cab real well with some type of coating. Eastwood makes some good products and extension hoses to reach the deep places. I'll have to do my research on seam sealers and also preventative steps for the rockers and cab corners.

The only rain this thing will see when it's done is a wash.
