Thanks for the suggestions. They are very helpful. I could treat the insides with Xtrol and then prime and paint them and the outside, in paint (I like the Satin Two pack Craig) as that maybe more flexible on the front edge than powder coating.

However, there is a large and well equipped coatings place near me (they do all types) and I could ask about the 'softer' type of powder coating, as Rob suggests.

Is the POR tougher still?
