4) Once you have prepared the side plates, place them on the sides of the hood so that the tabs are on the outside, and see how they fit. Thereâ??s probably going to be some gaps, and thatâ??s ok. Thatâ??s why youâ??ll be using the epoxy or whatever you came up with to seal it later. Itâ??s not critical what you use to seal the cracks either. It just needs to be hard and something you can paint over. I built two of these so far and I used some old bondo from the garage on my second one. Anyway, with the side plates propped up where they need to be, mark where you will need to drill the reflector so you can rivet. Once you have drilled out the necessary holes, use the rivet gun to secure the sides onto the reflector. This is all very wordy and seems pretty hard, but the project isnâ??t really that tough when you actually do it.
