I'm removing and replacing my lower firewall in order to have easy access to replace my lower weldments in my RV-4, and the upper and lower firewall have been attached to each other with a firewall sealant before they were riveted together (sealant has been applied under the entire folded-over lip, the entire length of the FW). I was only going to replace the lower firewall, but the sealant the original builder used has become quite firm over the years, and I'm questioning how and if I can cut them apart. My plan would be to use a blade and slice the sealant; however, the recessed rivet holes will prevent the blade's travel.
Any suggestions? Or should I just replace both the upper and lower FW together while I'm at it?
Anyone know what kind of sealant this is? Color is a dirty chocolate color.
Thanks in advance for the help.
