Hi guys, I know there are lots of people here from the states and so there are lots of great brands of finishing polys there. But I'm from Spain and here things are being a little hard for me. Transparency: It's quite common to buy products that say they are crystal clear but when you use it onto dark woods they change the color tone. Scratch-resistant: Same thing in here. I've tried several floor polys with the best Taber and Koenig rates (quideva, bona...), but they hardly pass the "nail" test. Easy available in Europe: Yeah, I've heard about GF Enduro clear poly, Varathane Rust-Oleum, Crystalac... but when it comes to shipping costs rise obviously. I'd love to hear your preferred options. Take care.
