How would you paint your undercarriage?

I don't have a lift. The cheapest option is drive each end on ramps and just paint what I can get to. I imagine there will be some places I can't access. Has anyone done this?

Are there other options? If I took it to a shop, how would that go and what would it cost?

Obviously taking the body off is the solution but I'm not sure I can handle that right now.

I did this, except with some Corroseal and chassis paint in between. Bit time consuming when done right...

I vote for dry-ice blast followed by waxoyl/dinitrol/Wurth/your favorite waxy underbody coating. No foamy stuff. POR15, Rustoleum, paint optional. Before waxy coating of course.

Taking off most of the body is a snap. Front clip is a couple hours, main body not much either. But there's also a lot of clearance otherwsie. Front clip removal really makes it easy.. but hey, isn't that part soaked in oil anyway?

I removed all body but the firewall/bulkhead ... wire wheel and por-15. Por 15 is a good paint and durable. But if painted over clean or painted metal doesn't adhere well/at all. Comes off like strips of tape first time you pressure wash an edge. No reason or benefit from waxoyliong AND painting at all. Waxoyl will, at most, soften your paint. If your paint fails.. it takes the waxoyl with it. Why? I understand waxoyl, i've used waxoyl, I no longer use waxoyl. I know better than to badmouth it on a british car forum. Waxoyl and their followers would have me executed.

Whatever you can do to the inside. Spray some ospho with a wand sprayer would do well. make sure your drains are clear at all times. Ospho is good, finish stores have better stuff.. but its more like $60 a litre.

If you want to waxoyl.. follow rovertek's instructions. Make your own waxoyl. It is simple as mixing a drink. If you plan on keeping the vehicle for a long time and paying for application annually or so... buy a galvanized frame.

DINITROL.

DINITROL RUSTPROOFING KIT - LARGE CAR | Rejel Store | Supplier to the Automotive Industry

I am looking into bringing a couple kits from the UK.

If you are going to do the underside of your Rover, this is as good as it gets. It's superior to Waxol. (think of it as Waxol being old technology) You need to get it properly cleaned, you can do the application on axle stands. Watch the video.

https://youtu.be/dDl6CDjW0KI

If there's enough interest, I'll bring in more and offer them up for anyone who is interested. Shipping form the UK on aerosol and chemicals isn't easy, unless you throw it on a boat and don't expect to see it in 3 + months (even then, with the chemical compounds, it's not straight forward). I'm hoping to have all the details worked out in the next few days.

Waxoyl is easy. I have done about 6 trucks. Follow the advice from Rovers North. If you go this route make sure you have a bottle of veggie oil for clean up.

It's the chemical make up of the products. Give it time, and something will surpass what works best today.

they way I do it it takes about 45 minutes of pressure washing on a Friday night. Park on ramps and blow out the chassis with leaf blower and pressured air. I tape everything with paper and tape (about 1 hour) on Saturday. It takes about 2 hours to spray with set up and clean up taking the majority of the time. If you want me to do it PM me or just come get my guns and do it yourself.

Underside steam clean was actually done to mine before it was imported from Germany last year. (Federal requirement that the underside has to be steam cleaned and completely clean of all dirt and debris.) Amazing how much surface rust and peeling paint hides under the dirt and grime, mostly only light surface rust though.
