I only ordered the iron phosphate as a cleaner. This is what was recommended for aluminum as well as steel on this site. The chromate was listed as a finish that could be applied to aluminum, if I read this right. I do notice in some of the threads, that chromate is the suggested prep by the experienced guys. If I don't get good results initially, I will order this next time.
I mill these aluminum parts with holes and cut the parts to the size I need with a bandsaw. Prior to polishing, I had always sanded these completely to 400 grit with a random orbital sander. Would this surface, along with the phosphate bath give me enough adhesion? Should I only sand to 220?
Just curious as to your recommendations. The sale of these parts are what will afford me a blasting rig, but I need a method that will get me at least good adhesion other than sandblasting initially.
I purchased some of the "Lab Metal" to use at the rear corner of the guard tails where there is a bend. I want to use this to seal this crack. It won't be but maybe a 1/16" bead tops. Do I P/C with this stuff freshly applied (read wet) and hope that enough powder will stick to it? Do I cure the lab metal first and hope that it will hold enough powder to be coated? Anyone technically savvy or have experience with this Lab Metal and P/Cing?
Thanks a lot Guys.
