Hi,
I'm concerned to read your post about Protecta-kote not being robust enough for your needs. We've sold a lot of it, and all the feedback so far has been positive. Did you give it two coats, at right angles to one another ? Did you know that unlike other such products, damage to the Protecta-kote lining is simple to repair, without any need to strip and re-coat ? This might be the answer to your problem.
Yours, Andrew
