View Full Version : Sign plywood

12-21-2005, 08:05 AM
I have to pick up some 4 x 8 sheets of plywood to apply some vinyl letters to for a job sign. What do you recomend for this? It is an exterior sign and the vinyl will show any cracks in the plywood.

I can either go with an AB exterior ply or MDF, but does MDF hold up good in the weather?

MDO is what you need.

The standard varieties of MDF are NOT weather resistant! I'd agree that MDO is the way to go...

MDO is used for highway signs. It should fill the bill.

I used MDO for the decks and bulkheads on my last boat. I'll never use anything else again. It's a JOY to work with, but as mentioned, make sure you use the "surfaced two sides" (S2S) version.
