AYC: To seal or not to seal

[l.i.fish.in.vt]

Capesam. at one point in my life i did a lot of work for a sign company here in VT. all the signs were painted with bin primer and still are. a lot of the signs were magahany or pine, hand carved, there was never any problem with paint peeling. the signs are all over the east coast, from Universal Studios in Fla to places on the cape and the islands,many see direct exposure to the elements.i think your freinds problem was that he''was in a hurry'', not the primer. for instance, you by trim boards, say pine, you don't break the surface with sand paper before priming. you can have adhesion problems. you know as well as anybody hast makes waste.
