Hi 911-Hotrod,

I just found out that the same company that makes Chassis Saver also makes Monstaliner. So, I was investigating if I could apply monstaliner directly onto Chassis Saver and this is what I found...

If your bed has minor rusted areas, Monstaliner can be applied directly over rust. Proceed with taping/masking in Step 6. If extensive rust is present, it is advisable to first coat these areas using Magnet Chassis Saver #934 Aluminum Rust Preventive Truck & Auto Underbody Coating. Apply 2 coats of #934 and allow to dry overnight before applying Monstaliner. Contact your dealer or Magnet Paints technical services with rust related questions or for further information.

So, it looks like there really is not a need for a etch primer as I can apply Monstaliner right to Chassis Saver. I did call and talk to their technical team already. But I will call them again and ask if it is advisable to sand 24 hours after last coat of Chassis Saver.

Thanks,

Rodney
