As most people know, if you have an M35A3 with an atrocious riveted steel hood, they rust and corrode badly on the bottom side. One factor is the inssulation that is riveted under the hood which tends to trap water. Water also gets under the rivets and under the central band of steel holding the two halves together.
I was able to get an NOS A3 steel hood from Carnac at the Georgia Rally this year. I was thinking about having spray in bedliner applied to the underside of the hood before I install the insulation. I would think this would significantly reduce the chances for rust and corrosion. Has anyone else done this with spray in bedliner or with undercoating? It would probably be even better to spray it on the top as well to really seal up the rivets and the band of steel, but this would change the appearance.
