Hell of a write up. Thank you very much for your input!
Oh, one thing I did read is once you got the propellant into the can, it will only last about 24 hours, before its no longer any good. Can you confirm this?
The black I have is just the air dry product which I intend on using on my Honda's wiper arms the black your thinking of using is catalyzed so once you pierce the internal hardener canister you will need to use it within 24 hours and that version will outperform the stuff I have because it is a catalyzed paint. Hope that helps.
