So Im thinking that after I've steam cleaned all the underside of the jeep, and attended to the odd tinworm, I need to put something protective on the chassis and under body.
Recently on non offroaders ive used Bilt Hambers excellent range of protective waxs, but i think id like to use a tough under body protectant first for the cj7.
Yrs ago i used the Schutz underbody spray on "underseal" stuff, wasnt bad but not excellent - has anyone got an modern products that they would recommend to put on before spraying underbody wax?

Have a look at dinitrol or waxoyl

I tested a load of those finishes in salt fog chambers at work for a project.
'Spray on stonechip' performed best; and that included spraying over rust.
It's now made by hammerite. Also I used regular black hammerite on my chassis years ago. Lasted well but too shiny!

i use old oil

That's what my XJ uses when it "self-preserves" much of its underside...

For what it's worth, I used Hammerlite, mixed with a flat black 'rust inhibiting' paint and the result was very encouraging, to say the least. Steam cleaned everything underneath of the Patrol, blew off the residue water with the air nozzle, parked her in the garage for a day or so and attacked any surface rust with the Dremel and wire wheel. I applied it all with a 1" brush which took a while, but allowed me to get at all the tight spots...the result was a tidy black, but not really shiny gloss coverage. We don't use salt over here, but the sand is pretty abrasive and can usually remove paint quite quickly...4 years later and it was still looking good!
70/30 mix worked for me and the recently aquired Golf will be getting the same treatment next week.
Can't comment on how oil leaks might affect the paint job...never had any!! :003:

I used chassis enamel paint, when it's covered in mud a jet wash just knocks the mud off, the old waxoil makes the mud stick more. plus enamel paint saves oily hands and clothes gained from waxoil

Don't be tempted to apply any of these new fangled 3mm thick polyurethane coatings to the underside of your truck. If it gets ripped or scored the damned stuff springs back in place and you can't spot it, but it allows moisture in and holds it there. Then one day you find a panel that feels a bit spongy but by that time its rotted right through and you can fit your fist in the hole.
Right spoiled my day I can tell you!

I'll stick with my method...worked very well before, so no reason to change it.
Still waiting to get my car back though....... :jpshakehead:

In this instance I'm with the Blue Oyster !!!

Yup, like I wish I'd said before:
"Paint or oil GOOD;
Thick rubbery 'urethane BAD".
Not to worry, we all meant the same thing!
