I bought 1 X 6 boards to redo my deck. Well 2 1/2 years later the wood looks as good as the first day. I did seal it 3 times.Wood I bought from Lowes after 3 years was splitting and cracking and yes that was sealed also.
Had everything I needed , great people and great service !!!!!
They will charge you to cut the lumber you buy there. Other hardware stores will do it for free.
