Contact info for the rust bullet crowd below.
I first came across it a good few years ago in a local boatyard where they people mentioned below were located before they moved. I seen a boat roof that was bare metal. 1/2 the roof was an expensive metal paint I can't remember what and 1/2 was rust bullet. Now 5 years on the rust bullet looks the EXACT same way it did the day it was done and the other 1/2 is covered in surface rust.
It almost looks like a galvanised effect when done. I hit it with a lump hammer to see and it didn't break (unknown to me the owner was in the boat so I left a bit sharpish!!

It's savage stuff. I plan to do the whole underside of the car in it.

I used that rustbullet stuff on my suspension/subframes/axle and a few other bits. Thought the finish would have been better tbh, but as long as the rust stays away I'll be happy enough.

Undersealing your car is not a small job, if I was you I would use shultz like dinitrol on the repaired area and then waxoyl over everything when thats dried.

The hardest part is getting rid of the wax thats been on the car since new.

I know in a perfect world, it'd be great to have our shells up on a rotisserie and get it back to bare metal and start from there with the best products.

However, this is not an option for most of us, it is a **** of a job to prep the underside of a car for any of these undersealers, when you havent got the resources available to do this, I think waxoyl does the job fine!

Do you want to eat your dinner off the underside of the car or do you want to stop it from rusting?

Anybody interested in doing work on the underbody of a car should buy this, it is the best underseal / stonechip I have ever used / tested by far, it is extremely flexable yet tough and you can match the original underseal texture with including brush finished edges etc, can be overpainted or left as is if you wish. I used it when I was doing the work on my G40.

Cheers GS, I bought it that time you recommended it!
