Internal Frame Coating Aerosol | Internal chassiss Frame Rust Remover | Rust Converter and Prevention Aerosol Spray Undercoating for Vehicles |14 Oz, Black

coats very well. The 360 spray wand makes sure that everything gets coated inside . Dries very fast to , just be careful not to be under a pinch weld when applying .It fines any gap and tends to drip . Other than that it works great . easy to use .

The product works as intended. Good coverage and reach with the plastic hose. Allowed me to reach entire length of 5’ GM a body doors

Used this on my 20 year old SUV. Easy to use, just make sure to wear protective equipment (long gloves, eye protection, floor barrier, etc.) and plug/unplug up the holes in the frame as you progress down the frame channels. I used the blue painters tape to plug up the holes. I unwound and straightened a metal close hanger and taped it to the supplied plastic extension tube to give me better control when spraying inside the frame channels. It's easy to use. It seems expensive but it can add many years of life to your vehicle. For the outside of the frame channels I used POR 15.

The tube by itself has no support so it flails all over and doesn't get paint where you want it. Straighten a clothes hanger and tape it to the tube and you'll be able to control where the paint ends up better. This system with the tube works well, it has 4 nozzles at the end the paint is expelled from. I do wish it had 6 or 8 so it got a more consistent coverage inside. You end up having to just take more passes rotating a bit each time when you can. The paint comes out with okay pressure when it gets to the nozzles in the end, I do wish it was a little stronger. You're limited however because the nozzles can only let so much out and there is a residual amount of pressure left in the tube after you let off the can nozzle, you will see what I mean when you try it. It causes it to spray 3-4 seconds longer than you're pressing the nozzle. Make sure you are wearing a respirator and goggles at the least, I even had a face shield on as well. The last thing you want is the tube to get away from you while you're spraying! You'll be telling a funny story for a good week if it does because this stuff sticks as well to skin if not better than metal. (Don't ask how I know!) Overall I feel like this did a good job and I'd recommend it to any DIY vehicle rust restoration. For reference I used 3 cans to do the back half of a boxed in 2013 Chevy 2500 frame and was able to cover everything well, see pics.

Good stuff
