what to paint inside frame rails

[Kent]

Hi Guys,

 

I currently have my 240K (yep.. K.. but the first 3 digits are right!) up on the rotisserie at the moment.. The car was sandblasted top and bottom, and i am trying to save a bit by painting the underbody myself before bending over for rust and paint. Underside was quite good.. but far from perfect

 

I have sprayed the underside in 2 coats of dupont epoxy primer (840R), and then a couple of coats of 3m water-based stone guard underbody spray ( with a few more to go). I would like to spray inside the frame rails whilst the car is on the rotisserie, but i am not sure what with..

 

i did a general search on the net for what to use, but most of the solutions do not appear to be available in Australia (like Eastwood internal frame coating etc. - i have had a BAD experience with POR15 before, so wouldn't trust that..). Does anyone have any suggestions? i do have a euro 1L style gun that came with a lance.

 

i really don't want to spend $12k+ in bodywork and paint for this car to rust from the inside out (and probably paranoid )..

 

Thanks Guys

Try rustbullet. Doesnt require much prep.

 

As wirh POR15 it works well but you need to follow the 3 step system or else it peels off.

 

I would just use cavity wax inside the frame rails using a 360 degree nozzle.

I used this stuff. http://www.knockout-rust.com.au/information.html

 

I applied it initially before I fitted the rails and sills, then afterwards although it was very easy to weld through.

Filled my Z with lanolin. Runs out for days and doesn't smell and is easy to clean up on the outside. Have you ever seen a rusty sheep.
