Rain Guard Water SealersCR-0608 Blok-Lok Concentrate Sealer Covering Up to 750 Sq. Ft. on All Block Surfaces. 1 Quart Clear Penetrating Silane and Siloxane Professional Grade.

Used this to seal my deck and also sprayed 5 fence boards 8 months ago to see how it would work long term.

The container received by me today looks substantially different than the one pictured. The description is different. There is no part number on the bottle. There is no mention of silane/siloxane chemicals. How can I be sure I've got the right stuff or did I get a knock off??
