On a mast especially, you need a paint with exceptional flexibility...cheap spray can paint isn't going to cut it. There is a good reason why Awlgrip costs what it does and enjoys the reputation it does.
Remember the line..."Never enough time and money to do it right the first time but always enough to redo it right the second time."
I have been doing some homework on this and Awlgrip, Interlux, Glidden, and a few other noted brands are all owned by the same company AkzoNobel.
