SPRAY RUST KILLER

Dinitrol has recently launched a new aerosol version of their RC rust converter compound, named RC900. Putting rust converter in a spray form is actually a very practical idea. It makes it easy to treat inaccessible areas, such as door bottoms or inside wheelarches, and it's much less messy than the conventional paint-on stuff. It also avoids one of my pet hates: which is that any brush used to apply rust converter always has to be thrown away, because it's impossible to get the stuff out afterwards. And it dries hard.
RC900 converts rust to a hard black inert compound, which is perfect for painting, or applying protective wax, over. Unlike a normal primer, the black stuff is chemically created and will not rust again – even if becomes wet.
