I've still got factory hood, with the 16 year old foamy stuff attached to it and its looking pretty rough (hanging down and stuff). I was wondering if i should just pull it off or does it serve some kind of purpose.
I’ve ran without the lining attached to the bottom of the metal OEM hood for 3 yrs and never saw any sign of discoloration of the paint because the lining was there.
The last 2 yrs I haven't had the lining under my fiberglass hood and to date I'm not seeing any discoloration or ill effects from not having the lining under the fiberglass hood.
I got rid of it on my last car. This one it is still in good condition so I haven't ditched it yet. Supposidly it is also there as a fire retardant. The little plastic clips will melt and drop the cloth onto the engine. I don't know how well that works and I figure that an engine fire will spread no matter what falls on it.
