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!

Great product, got the red dirt off my 4X4.

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

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.

Performed the removal dirt and grime on our 4wd and van from our 4 month trip. However I may need to be more vigorous in the rinsing off as it left a dirty film on the van. Will see how it performs next wash.
