Beautiful work Shine. I like wood -- dashes, consoles, steering wheels, etc. The '87 Corvette I bought in '91 (and still drive) already had the wood dash and console but I added the steering wheel. The tiny storage space under the convertible top was filled with a carpeted wooden box with speakers, subwoofers and a CD changer in it. When I ripped it out, I discovered that convertible Vettes didn't have storage bins or doors (I think the original speakers filled the space). I put the coupe storage doors in and made some mahogany plywood panels to cover them (instead of carpet pieces). I normally finish woodwork with a dozen or so coats of marine varnish with lots of wet sanding between coats. Because the doors get stuff piled on them, I chose to use casting resin this time. It seems to be holding up and it's pretty easy to buff out scratches. Have you ever used casting resin on your woodwork?
as far as i know the ex74 is the only uv one. may have changed . i spent a lot of time on the phone with one of the tech people there . the finish would get real soft in sun lite then go back rock hard and clear when cooled. they were developing the ex74 then for uv protection.
