Ospho go bad?

[ramdough]

Ok, I was pulling off my front skid plate and noticed the casting for the front right spring perch (M1083) had blistering paint. I chipped it all off as best I could (hard to get at), blew the dust off, then painted on ospho. Last time I used ospho, I saw instant fizzing. This time, nothing. It did fizz on the concrete, but that was the only reaction I saw.


My bottle is probably 2-3 years old.

Did it go bad or am I just impatient?

The second....

Phosphoric acid in a bottle (any % dilution) will last forever, even if not hermetically sealed.

Thanks!

Do you think I can prime tonight, or should I wait longer?
