Built to Handle Solvents
Our heavy-duty pump sprayer is solvent resistant, making it perfect not only for Underbody Protection Spray but also for applying Tyre Shine and other protective products.

The log bridge on the Old Telegraph Track (OTT) in Cape York is an iconic, precarious, and often nerve-wracking river crossing located at Cypress Creek. It consists of narrow logs, often reinforced with ratchet straps, spanning a significant drop. It is known for being shaky and requiring careful spotting to navigate safely.

Amazing result. Really easy to thread through chassis. Flushed out an astonishing amount of mud and grit

Customer photo review of Triple Protection Bundle 5lt

I picked up Groundswell’s Triple Protection Bundle and I’m seriously impressed. I’ve used the Offroad Wash and Underbody Spray before and absolutely love them — after my last trip to Teewah Beach there was barely any sand left on the car! I’m heading to Fraser next, and after trying out the new Offroad Protective Sealer, I feel like my car is properly sorted and ready to go. Honestly, couldn’t recommend these products enough. Groundswell, you guys are killing it!

Triple Protection Bundle 5lt

A much better way to spray the underside of your vehicle than the trigger operated sprayers. Also great that it’s solvent resistant.

Solvent Pump Sprayer 1lt

The pump up pressure sprayer is much easier to apply an even coating than the trigger type sprayer.

Excellent service provide by these guys. Snow Foam Cannon arrived just before Xmas but was damaged during transit to WA. Emailed them and a replacement was sent within a week during the busy Xmas/New Year period. New gun works brilliantly.

Works well but I wouldn't say it works any better than some of my other products that weren't designed to get rid of red dirt.

Mud Red Dirt Wash

Get product, amazing service, very effective coating. Keep up the great work.

Works too well. The amount of sand that came out of the chassis was amazing. Cant wait to go beach driving again just to use it.
