Undercoating-gun question

[blackdograv]

I'm going to undercoat my Rav4 with heated cosmoline.
Here's an undercoating gun on amazon:
Astro Pneumatic 4538 Economy Air Undercoat Gun - Amazon.com

There does not appear to be any container with the gun.
Has anyone used one of these and can you advise what the undercoating liquid goes in?

Also, instead of cosmoline, I am thinking of using this product, or something similar.
Has anyone used this or have other recommendations for non-grease product?

It uses the normal cup, it is the nozzle and pressure setting that makes that special. We have used bedliner in our shop, but the components you are applying this to have to be cleaned up, no surface rust, dirt or moisture, and adhere to the dry time.

I guess I don't know what you mean by "it uses the normal cup " My question related to the fact that there is apparently NO cup with this gun. Are you saying that there is a "standard " cup which can be purchased separately?

Yes.....you should be able to buy a separate canister for the gun. I ran into trouble after buying just the sprayer portion and couldn't find the oddball size canister for it. My advice..... buy a complete gun kit.....
