I've used the AC on only a few small jobs looked good and lots of people have good results with it. It's a little pricey than what I'm used of paying but If you can get the $$ for the job that's even better. I just do a ton of fences and it's hard to get the $$ for a fence when you are paying $200 for 5 gal of AC the sealer store. Did it go up? Yikes I only pay $120 for 5 gallons of the Gray Away but my shipping is cheap since I truck it in from Dallas by the pallet to here in Houston.
You know Charlie with Apex decksavers he's in your climate in NC and he uses a mixture of stains from AC to TWP to Wood Tux. This is going on almost 20 yrs for me and the Gray Away is all I know and used almost $30K of it in 2014 so it works for me.
I think the products you use should be consistent and if you give your customers to many options sometimes they get confused and it's tough for you to keep an inventory of products so I would stick with 1 stain 2 at the most.
What are you looking to do more decks are they mostly pine or some hardwoods or even doing fences?
I would post some old cedar pics but I get and ERROR when uploading pics? I can't post a link also from a photo host either Beth?
I'm also a acrylic free zone....
