    I think the undercoating on my 67 Charger is probably as old as the car and has turned a dirty looking tan/gray color. Can I apply any of your products over the old undercoating? Removing all that stuff would be a royal pain in the ass. If I could use any of your undercoatings or paints over it that would make my day.

  2. The Shutz Underseal gun just has 45-150psi on the box. What is the recommended pressure for spraying Undercoater? What things should I be looking for when fine tuning the pressure from the recommendation? Do you have any data for SCFM requirements for the Shutz gun? Just want to make sure my compressor can keep up.

    I'm looking to purchase some undercoating but before I do I want to make sure I can paint over it. Can any of your undercoatings be painted over?

    I'm looking to paint the bed of my truck with Rust Seal and then top coat it with the Rubberized Undercoating or Bed Renu. I've used the Rubberized Undercoating before and I really like it but wondering what will be more durable in the bed of a truck?

    I see you have a rubberized and a solvent based asphalt undercoating. I'm using this for my wheel wells. What would you recommend for this job?

    I want to use some of your undercoating and I was wondering if I should put the Rust Seal down first and then apply the undercoating over it. Let me know what you think would be best.

    I'm about to do the 3 step RustSeal on the underside of my Kubota mower deck. I've been fighting peeling paint and rust for a number of years, tried POR15, Kubota Orange, and others with little success. My question,, has anyone ever used KBS Undercoat Solvent Based Rubberized Undercoating on the underside of a mower deck? I'm confident that RustSeal will out perform the previous paints,, wondering if top coating RustSeal with the undercoat would be of any benefit?

  10. Can the Rubberized Undercoating and the Asphalt Undercoating be sprayed through a regular spray gun?

    Any plans for a truck bed liner product? Or could one of your undercoat product work as a bed liner?

  13. Is the finished surface smooth like paint, or rough like bedliner coatings?

    I sprayed a gallon of undercoating on the bottom of a vehicle but ran out of material before I finished. Since nobody carries this locally, I ordered another gallon to finish. My question is since it will be several days between painting, do I put a small amount of thinner over the already dried coat to get the new coat to stick? Or will it stick to a coat 3 days old by itself? Or will it not stick at all to the first coat? I was only able to do one coat and in some areas you can see through so it will need to be touched up with a second coat. Thanks.
