We used Valspar direct to metal(DTM204) primer and its high solids
corresponding two part polyurethane top coat and it worked well without any
other surface preparation. One should be certain to have the proper

Well that is not unexpected news. I am really glad to hear it. It is really a

I guess we can all move forward now, (i never stopped).
