    OK so on my travels on the interwebs I was reading about treatment of micarda (pls excuse my bad spelling).

    This is supposed to make it even more water proof and give it a high shine. My question is this....

    Wouldn't it make it highly poisonous as well while curing adding this onto the polyester resan or fiberglass resan?

    Pb.

    P.s. again please excuse my crappy spelling.

    The resin in the Micarta has done all of its venting during the curing process +7 days. Putting Polyurethane on should be no problem as the handle material is fairly inactive. Now if you were to get bubbling and other odd reactions then there may be something to worry about but for this combination there is no reaction.
    If you were to go with a spray on clear epoxy coat then there would be concerns in regards to full respirator and powered ventilation etc. that goes along with some fancy paints.

    Depending on the Micarta, I just sand and buff it. No need to seal it, after all it already waterproof.

    WARNING: If it's burlap, canvas, ivory linen/paper or any other light colour DO NOT buff with compound. This will get microscopic grit in all and any pores and you'll be forever stuck with it. I use Meguiar's Scratch-X and a clean rag.

    Black, brown, camo and dark coloured Micarta just needs some fine sanding and time on the buffing wheel and it shines.

    Nice warning there, about a week too late for me. Should have known better but was in a rhythm and ended up with a pink handle with blue embedded particles, looks dirty to say the least.

    OK thank you guys I thunk in this case I'm just going to let it sit for a bit then sand. Was just very worried about negative reactions and such.

    Once the phenolic resin in Micarta is set it doesn't react very much with most chemicals. We use it in Oil & Gas. I can't imagine it would be any more poisonous than the solvent that is in the polyurethane (naptha?). This gasses off as the polyurethane hardens. It should be used in a well ventilated area. For the record, we've put polyurethane by the gallon on our hardwood floors and our kids have the right number of toes. Mind you we weren't exactly watching TV in the living room while it dried. ;-) And if we were I don't remember being there. LOL
