I didn't mention it but one reason I choose Waterlox for this piece is that at any time I can easily recoat and the finish will burn into itself. So, if I notice the finish needs a new coat to freshen it up it is a simple process of cleaning, scuffing and applying an additional coat or two.
I used Waterlox marine on our exterior door and simply clean and apply an additional coat of finish every year or two.
TIP
Squeeze the air out of the can as you use the finish to keep the remaining finish in the can from gelling. I keep the small metal cap which is pried out of the lid of the can before use. I use what finish I need then squeeze the can bringing the remaining waterlox up to the very top of the can then replace the small metal cap, followed by the screw cap. If I have used a fair amount of finish I tend to use a wood clamp to squeeze the can. Yes, this makes my waterlox can look terrible but I have kept finish for years with this method. Many waterlox users complain that the finish gels quickly and they only use a fraction of the product.... You will not have this issue if you follow this tip!
