I understand that one can charge up spray cans, Ive never tried it.

I made an adapter to recharge my paint rattle cans:

It screws into the valve of a propane torch. I.e., in place of the
tube. In use, I wear rubber gloves and wrap the can in a rag - there
will be leakage.

There are two types of valves on pressurized cans - inies & outies.
This is for inies & might not work on the Dykem cans.
