Overall I really like the stain and sealer, the number one asset being the non toxicity. It's easy to mix and apply and worked well. It's hard to say how long it will last - the deck (cedar) is on a full southern exposure with no cover at all. Conventional stains in the past have lasted only two years or so - if I get that out if this product I'll be happy.
The hard sell on this product is the amount of work involved. My deck is 32 x 12 with railings and balusters the whole way 'round. Having to apply two coats of stain and them go over the entire thing again with sealer is no fun considering a conventional stain would cover it in one pass. It's literally 3X the work. Having said that - seeing my children and pets spending time out there and knowing they are not breathing in noxious off gassing chemicals is something you can't really put a value on so for me it's worth the extra effort. It would be great if they could incorporate the stain and sealer into one product - I considered trying to mix them to save some time but I didn't want to compromise my experiment with the product.
All in all it's a good choice for me and I will use it again and recommend it to others while sharing time on the deck that's not killing us as we talk about it!
