Spar-urathane, 3 coats sanding inbtwn coats works wonders

You can also paint the inside of the canopy white to help reflect more light and once dry that also can be coated with the polyurathane

yeah i was thinking polyurathane

If you don't let the poly dry for at least a 2 weeks it won't be dry... This is if you use enough like 3 coats.. THen you won't ever have to worry about moisture... With 1 coat after a year the salt will have sanded it down... I use RID primer personally...

If your using it inside a hood you really dont need 3 coats. Sanding in between gives the poly a nice smooth finish. Home Depot and Lowes sell a spray paint can of poly. One coat would be fine. When I build bars I do 4 coats and sand in between to smooth out the finish and make it as durable as possible. But one coat is good enough for you.

 

[Bob 1000]

I say 3 cots so that it last for ever and so that you get a decent reflective surface.. I used 2 coats on my last bathroom vanity and it almost sanded of after 2 years and that's freshwater... You do the math...

 

[georgelc86]

I guess it depends on the application because the bars that I do 3coats on, some 4, dont last forever either. They still have to be redone nearly every two years. Either way duke, poly is the way to go whether you choose 1 coat or 22.
