He Came Up With A Way To Stop Rust On Old Pickup
“My 1990 Chevrolet Silverado 1500 pickup was covered with rust at the bottom on both sides. I didn’t want to trade it in so I came up with a way to use spray-on insulation to paint over the rust and seal out moisture so it can’t reach the metal. This method lets me keep a vehicle going for many more years,” says Kenny Hinnenkamp, Melrose, Minn.
  He first experimented with the idea 8 years ago on one of the pickup’s fenders, using a special plastic tool he made to apply the insulation. Then 2 years ago he replaced a much bigger area of rust on the body where the metal was completely gone. He first used Styrofoam insulation to fill in the rusted-out holes, and then covered the Styrofoam with the spray-on insulation. Both ideas have worked so well that he recently began providing “how to” plans.
  “It lets anyone do their own rust prevention body work for $300 to $600, instead of spending up to $8,000 at a body shop,” says Hinnenkamp. “Your vehicle should be able to go another 10 years without rust forming. I painted a rusty fender on my pickup 8 years ago, and I haven’t seen one bit of rust since then, so I know it lasts.”
  He says the spray-on insulation “seal coats” metal to keep out moisture, and is salt-resistant so once it’s on there’s no way for moisture or salt to cause corrosion. “Spray-on insulation isn’t supposed to be painted over, but I found the substance is paintable so I can paint it a different color any time I want,” says Hinnenkamp.
