I recently bought a ten inch FranTom saw. It didn't have a hood, so a built one of luan with a plexiglas window in the top. I want to waterproof the inside, but I'm not sure what the best method is. I went to the hardware store to check on fiberglassing material, but they only had a gallon of fiberglass resin for $40. They didn't have any fiberglass cloth. I've never done any fiberglassing, but I think you need both parts. They guy working in the store recommended spraying undercoating for rustproofing cars. Are either of these options good, or is there a better way to waterproof?

My father-in-law just suggested that I use a spray sealant like they used to advertise on TV. Do you remember the ad where the guy has a screen door on the bottom of a boat and sprays it with some stuff and then in floats? I usually don't believe ads for stuff like that, but it might work in my situation. He said he saw some at Kmart. Have any of you ever used something like that?

If its to protect the wood I would use Helmsmen polyurethane. Its got UV inhibitors and is used to waterproof outdoor wooden parts of yachts. We aint got none them therr yachts but we do got them lil one man strip fishin boats here an we use Helmsmen to wsterproof da cracks an keep da boat from rottin. Works mighty fine!

are you going to use water or mineral oil as a lubricant? don't use a petroleum based sealer if using oil as a lube.

I'm planning to use water, but it would be nice to leave my options open. I think fiberglass might be the safest option. I don't know much about Helmsmen polyurethane, but regular polyurethane isn't super waterproof. Helmsmen sounds better if it's used on boats.

Chuck, that looks like a really good method of waterproofing, but I've already painted the wood. I'll have to remember that for other situations though. I bought some fiberglass cloth and resin this morning, but I'm waiting for paint to dry before applying it.
