Proseal Cartridges
These cartridges and nozzles be reused and reloaded with sealant mixed in bulk in your shop. ProSeal does not stick to polypropylene catridges and nozzles very well. After you are done dispensing, simply let it set up for a few days, and then remove the plunger and nozzle, demold the slug by using a blunt stick to push the slug out of the cartridge. Extra cartridges with plungers and nozzles were available from Aircraft Spruce or other adhesive supply houses.
I did my tanks this way, mixing from a can, loading the cartridges with sealant using a toungue depressor or wooden garden row stick label, dispensing with a pneumatic gun, and reusing the cartridge. Much more control on dispensing, made the whole tank experience kinda fun! No horror stories here... Can't wait to use the same setup for those misc upcoming fuselage Proseal tasks.
