Just curious if anyone here has added reinforcements or bracing to their shoebox hood? I have noticed that mine is heavy from the undercoating that was sprayed on it. When I open it and prop it open with the one steel prop it has, it flexes and is lopsided after propping open. Is this normal? I have read that people are quick to insist that you not weld anything to the hood cuz they are prone to warping from the heat. I would like to remove the undercoating, brace then paint it. My shoebox is a 1951 ford custom fordor. Any thoughts are appreciate on the matter.
