the thing would not budge with just marine silicone holding it on. had to cut all the way around to get it off. im pretty sure a strip of glass will do the trick
yup. Its called hard board I think. but its the same stuff that pegboard is made from, just no holes. And the pine I used as a frame was like $12 a bundle. I used less than 1 bundle. So far my cost is around $40.
