I am very disappointed in my descaler tool. I am hoping to persuade @dieseldog69 to try it on his motor for a second opinionI think I'd like first hand so I may not be able to get 100l but I'd have to see. I want it for undoing bolts more than anything but would also like to be able to expand on tools. The scaler tool would be beneficial but a lot of the rust is already gone! Spraying would be something I'd like to do. I know I wouldn't get workshop finish but I'd like to be able to spray rather than brush
