I am going to tackle replacing the VCG on my '91 Miata this weekend and have read conflicting information on what kind of “sealant” to use on the six specific location listed in the service manual.
The service manual simply states “high temperature silicone gasket sealant”
I did some research on the web and everybody seems to have differing opinions on black, blue, red, copper, non hardening, plyable etc.
from what I can make out permatex ultra black is the product of choice for this kind of job but not 100% sure.
Any help would be much appreciated
