You could always try -
www.por15.com - their company website
When I do my frame, etc. - I will be using the products on
www.nomorerust.com user msgross did his SWB rebuild using it and it turned out awesome - so awesome in fact that they put his pix on the company website! It seems to work just as well and can be purchased for a LOT less than POR-15. (Just throwing an option out there for you).
Here is the link to the forum post about it with pix:
