69Mach1 M code 20 Report post Posted December 7, 2023 Does anyone have a recommendation for a spray type undercoating for the undercarriage? I replaced the torque boxes and floor pans and would like to mimic the original appearance within reason. As we all know the original material is either tar or something that behaves close to it. I've got a few things in mind but was wondering how many have been down this road before. Quote Share this post Link to post Share on other sites

jmlay 80 Report post Posted December 8, 2023 My plan is to utilize SEM sprayable seam sealer. The gun price is outrageous but I found a used one locally for a very reasonable amount. Quote Share this post Link to post Share on other sites

Vicfreg 773 Report post Posted December 9, 2023 I used the SEM product for the inside of my front fenders, it is good stuff. I think the factory used 3M "Shutz". Quote Share this post Link to post Share on other sites
Vicfreg 773 Report post Posted December 9, 2023 Also not sure the cars were "undercoated". The Chassis and Weld and Sealant Assembly manuals should show what was used. Quote Share this post Link to post Share on other sites
