Cavity Wax?

-
I have some Eastwood "internal frame coating" (green) on hand but have not heard of "cavity wax" before now.

Rust Preventer Cavity Wax | SEM Products
I got the Eastwood frame coating for my car and best to cover everything that you don't want to get over spray on. Don't ask me how I know..
I like the cavity wax better for cleaning up but don't really know witch one would be better.
 
Boy!!! I'm really not comfortable with that name "Cavity Wax"???:poke::rofl::rofl::rofl:

Is that what they use on you right before a cavity search??
 
If you need cavity wax, you would have ProForm.

Great stuff for internal areas wher weather can't strip it off.
Wax or Paraffin-Based Undercoatings
A paraffin-based undercoating will be the cheapest and quickest option available with which to protect the undercarriage of your vehicle. However, keep in mind that it will wear off quicker than other types of undercoating and will need to be stripped and reapplied at least once every year.

Wax-based undercoatings never truly harden. During application, they drip or flow into seams and cracks to provide protective properties. They are usually available in a spray gun canister or in an aerosol can and offer at least a base protection in moderately humid climates.

It's what Bubba uses on you in prison right before he.....well....you know.
 
I bought some 3M version of the same and the instructions talk about flammability in the future. As in, it will burn if heated enough (welding etc)
 
Body shops have been using cavity was for a LONG time after repairs. The thing about cavity wax is that it "creeps" after you apply it. It wicks its way into hem flanges and other hidden areas. The best I've used is Seal Out. It comes in a pale and you can pump it into a siphon fed gun. This is done at low pressure.
 
....Eastwood "internal frame coating" (green)....
Lol, I tried that stuff on my truck out in the driveway. Sure glad I put a tarp under it. I would have had a lot of green exorcist pea soup puddles to clean up.
To get further into areas, I taped the nozzle and tubing onto a straightened heavy wire coat hanger with a bend so I could twist it around.
