[70 chevelle]

I sand the inside with some 120 grit then clean the dust as thouroughly as humanly possible. Clean it with some alcohol.Precut some 3 inch wide strips to do your corners and some sheets to do your flats. If you have never used fiberglass resin before you might want to use epoxy resin you can have a MUCH longer work time. Fiberglass resin sets very quickly. Mix your epoxy reisin and brush it into the corner then lay the strip into the corner allowing half of the strip to sit on either board of the angle. Once you have worked the air bubbles out of the corners you can start brushing the flat and lay your sheet down on the flat. I ususally do two layers and alternate between the corners and the flats. Depending on temperature it may take the epoxy over twenty four hours to dry. If you decide to do the epoxy resin make sure you use a weave and not a chopped matt. You can only use chopped matt with fiberglass resin. It's no too late to put that divider board in. Good luck hope this info helps.
