Made from an old plastic grease container and an original Shutz underseal can. I also had to shorten the gun pick-up pipe.
Prevents rust in: chassis cavities, welded tube cavities, hard to reach internal cavities (internal wheel arch seams, etc.).
Threaded connector is epoxied into the lid.
I use from a 50:50 mix to 75:25 (oil:white spirit) mix. Soaks into seams, small gap filling, never really dries. Long lasting. Great value. Easy clean-up.
