    Excellent protection - fussy aaplication

    The marine finish provides excellent protection for outdoor exposure, but achieving a smooth, consistent finish can be tricky. Allow extra time for any prior sealer coat to cure. I get best results thinning the finish 15% with mineral spirits and allowing 48 hours between coats. I sand with 320 grit after second coat and wipe on a 25% thinned final coat. If the material is too thick and skins over, it will not cure underneath. Do not use when humidity in your shop exceeds 50%.

    Great Product

    Both the sealer and finish are great products. The finish is long lasting, a few years if not in direct sun. I apply it a bit differently than the other reviewers. I wipe on with an applicator pad and then wipe down the surface with a microfiber cloth immediately after application. I build up several coats with this method (24h apart) and it gives a nice deep gloss that is also very warm. It will appear dull after the wipe-down but if you have sealed properly the gloss will rise as it cures. If you have never used this product before and like a more natural look I highly recommend giving it a try.

    Works very well for countertops

    apply thick coats so it levels itself

    Very thick, does not level properly

    On the advice of my local Woodcraft, I purchased this for outdoor furniture. It is very thick and, when applied as directed, did not level out. I called Waterlox and they said it should be about twice as thick as a normal varish but that it should have leveled out. Saddly, now I have to do a lot of sanding and find a new final finish.
