Sand blasted metal treated with Ospho but sitting for....

[Cranky]

about 20 days inside a fairly dry shop room. Should I do another treatment before painting? I don't see any rust accumulation......also, I'm planning on using epoxy primer for the next step. Destructions say to test a spot. Anyone done this with good results?

Paint shop said to clean/dust off anything that might be loose and go over it with wax and grease remover and lay on the primer......

GET RID OF THE OSPHO FIRST!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Re-treat the areas with ospho, while they are wet rinse with water to completely remove. Dry off, use a good waterborne wax and grease remover, followed by a solvent wax and grease remover, dry, and then spray epoxy.

If you do not get rid of the ospho first, adhesion problems will result. Every time.

Here is a forum to get all learned up- these guys make the best epoxy primer in the biz.
