Getting close to finishing up my new rear firewall. Any recommendations on a sealant that is flame retardant? I’ve used just a general purpose sealant in the past and would like to upgrade. This 3M seems solid but I strongly prefer something that is silver or black. I’ve also heard some of the flame retardant sealants get brittle and fall out due to vibration. Anyone experience this?
