Eastwood Rust Encapsulator w/ext Nozzle Black
Product Review (submitted on July 1, 2012):
I used the product with extension nozzle on the inner frame rails on a 64 1/2 Mustang convertible. I used a small diameter foot long spring to keep the plastic line straight. Went through the seat beat holes to get the back of the inner convertible frame rails. Used the nozzle extension to top coat also. Works great.
