Good Morning..........We are staining our home which has cedar siding. I have chosen my colors which are Ben Moore, but am concerned because there is a limited warranty on the can, the warranty states only for new wood. I will be power washing, drying for several days, then priming. Should I be concerned about this brand of stain? I know Olympic was given great reviews by Consumer Reports, but I did not like the colors. Olympic also had a great warranty. Any info would be appreciated............thank you
