Thanks guys. Otis - You are right. I always wear a dust mask when I'm in the shop and I have one with carbon filters for finishing. I'm also sensitive to loud noise. I hate going to affairs with bands. Good or bad they only have one sound level - VERY LOUD, I take ear plugs. I have good, sound deadening ear muffs that I wear when running my table saw, thickness planer or router and I have several pairs of safety glasses. One with magnifying lenses like bifocals. The older I get the more I need it. I'm very safety conscious and sometimes do practice runs if I'm not sure, before I actually make a cut.
But I digress. back to the question at hand. I has a "Duh!" moment and decided to contact Crystalac directly and ask the question so I sent an email with all the details. To my surprise I received a response asking me to call them to discuss it. I called this morning and spoke with David, a very knowledgeable and personable guy. I learned more about Crystalac as a company. They've been around for almost 30 years starting off with a different name. In that time they have only made Eco friendly water based products. Besides the grain filler they have sanding sealers, top coating and more. After we discussed it he recommended their sanding sealer and their Extreme poly that dries very hard, is self leveling and has UV stabilizers. And, apparently, a little goes a long way. To cover both sides of the 39" X 39" table with 3 to 4 coats it will only take a pint. I've read in a few places that, if possible, it's better to use products from the same manufacturer rather then mixing products so, I've decided to give it a try. I'll order their sanding sealer, I already have the grain filler, and their extreme poly and give it try on some scrap wood. That's the one kind of wood that I never run out of. Anyway, I'll stop rambling at this point and I will let you know in a couple of weeks how it works.
