Just wondering what people thought was the best stuff to protect the underside of your motor with?

what about wax oil? 

Or thay bitchumen stuff?

Sounds expensive tbh

Iv left the mag at work so I'll check the morra and see if there's any mention of costs. Apparently the Canadian army use it on there vehicles.

$119 dollars in the US, so i expect we'll be gang raped and it will be £500

Gonna have my car done at some point, so interested in this

13quod for a tin of underbody seal and a brush, save your money by not seeing a specialist,

Wirebursh all loose crud, then prep the rusty bits then apply coat
