Thread: Injecting Cavity Wax

schutz gun should work, no blockages anywhere.

would taking door off and entering through hinge holes work? You may be able to access top of bulkhead corner (rust prone)from top hinge as well

That might work too, but I've found a hole in the base of the A-pillar through which I can get a small diameter pipe right up to that top corner.
When I tried to undo the door hinge bolts I must have snapped a captive nut inside the pillar and the bolt is just spinning in the hole.

I'm just wondering what gun people have successfully used to get the wax atomised up inside the cavities?
Any suggestions will be greatly appreciated.

Ah - Timely post - I've just been rust treating my new Fender. I tried using that Valvoline cavity wax on my last Fender - with the Schultz gun. I could nto get it to work either - and it did the same to me. I ended up using a Kerosene Wash Gun, it's used for degreasing parts with air/kero. Worked really quite well. But I really think the problem was the cavity wax was too thick to spray well.

So this time - on my new one - I used some POR Rust preventative oil - it's basically non smelly fish oil. I used this with the Kero gun again , I could not find a spare connector for the Schultz gun, and again it worked really quite well. The oil is as thin as diesel, and spreads really well, it does not clump like that cavity waz did. The air pressure is enough to force the oil quite a distance.

I've also used the Valvoline Tectyl in a spray can and that worked well too. I've just not had much luck with spraying the heavy cavity wax.

I've done exactly what you've described. As long as the gun has the plastic nozzle still on it, extend with some of the clear plastic tube a bit smaller, heat in some water and stretch on. Once cooled it should stay on. Then if you need a smaller tube, make a reducer from some copper tube fitted in the same way.

Keep the cans as you can refill from bulk containers or use for other stuff like fish oil etc.
