Good Morning......this is a great site!!!!!! I received my colors from Caswell & am ready to go.... My question is the use of "Ospho" .. Is this similar to iron phosphate & ok to use? I use ospho now before painting with spray paints & it works well.....Thanks for the info..

I just read about it on a website...sounds like it will do the trick. Good luck
