Plexiglass
The quote that I got from Hunter last year was a lot higher than Michael got, and calling around for supplier of HDPE (High Density PolyEthyline), which is what Hunter told me to use, were not much better. I considered the cutting board route, until I read somewhere that the cutting boards are not UV stabalized, and would need replacing after a few seasons. Then I was bumming around in Home Depot and came across the plexiglas, and decided to give it a try. It cost less than $10, and I cut them out with a Dremel Tool. I installed them at the beginning of this season, and will see how they last. So far, so good.Rob,S/V KinshipH 23.5
