Re: Replacing Cowl Vent Gasket

I think it would be a good idea to take your time here too. It looks like getting the old gasket out will leave a good portion of raw steel exposed. Tape off the area not affected on the cowl first. Clean and sand the grooved area as smooth as practical. Then coat using metal etching primer, then an epoxy primer and then a top coat of spray paint. The colour only needs to be close as it is mostly blinded by the gasket and its vent.
This will properly seal up the gasket well's surface.
I know this all adds days to the project but doing it right is never a waste of time.
Once dry it will also allow a good surface for the adhesive to work at its best to hold the gasket in place and not allow any rust blemish to occur later on. No sense getting the new gasket in only to have issues later down the road as it is an area water lays in and takes a long time to dry, even washing the car introduces it as you will not likely be taking her out in the rain. Note too there are two drain pipes that help shed the water and these drain through the firewall with flexible hoses. With the gasket being as it is, they are likely rotted and embrittled too so you will likely need to have new hoses put on.
Have fun!
