well in my case if ur not gonna use that old jug of nitro. u can throw the body in and let it do its thing. come back and see ur results. dish soap it off when ur satisfied to remove the oils that come with the fuel. and ur set. way to go with the old bodies for sure, brake fluid is just too much of a risk for those. but BF does work great too as u can see above.
pick ur poison (literally)
