Eastwood Internal Frame Coating w/Spray Nozzle
Product Review (submitted on April 2, 2013):
I used to treat the insides of some rusty doors. Of course they are difficult to get inside, near corners and edges. The brilliant hose with nozzle (included) gets way back in all the areas you need. Label states states it stops rust and coats to prevent further rust. It is a nice thick coating. Caution; when the nozzle gets to an opening it sprays the walls, toolbox, me, etc. Pricey but considering the quality and time savings it is a great value.
