    Default Fiberglass hood refinishing.

    Need advise on proper way to finish my fiberglass hood.
    Hood was a 2.5 cowl for my 85 mustang but was to
    Low. So i cut the hood and raised hood to about 4.5 inches.

    I built up fiberglass from the back side to get my initial shape. Then i used shortstrand filler on the top side to get closer to final shape.

    I have rage ultra to use to get my final smooth finish.
    My question will rage ultra work ontop of sanded gelcoat. And what would be the right primer to use over the rage and gelcoat. I do have a cheap harbor freight spray gun with a 1.3 or 1.4 tip.

    Not sure on topcoat as of yet still have to do the rest of car.

    Thank you Scott20200202_151449.jpg

    The Rage will work but you should sand the glass first with some 80 grit or more coarse before applying the Rage. After sanding the Rage apply several coats of filler primer then guide coat and block sand with a fine grit before painting.

    Yes, Rage will work over gel coat. If this were in my shop I would hit repair area with 80g for a mechanical bite that extends well into the existing paint. Clean with grease and wax remover, apply Rage body filler and sand entire hood with 180g. Apply a quality epoxy primer followed by a quality HB primer.

    Spray Max makes a two part filler primer in an aerosol can but you may need more than one can to spray the entire hood then guide coat and block sand.

    i'd use the hf gun for the primer. it will go much better than spray cans. spray cans won't give the film build you will need, especially if you're trying to fill 80 grit scratch.
    i'd have sanded again with finer grits before primer. like 80 to 150 to 220, then prime. 80 grit will show through unless you skim coat the entire hood or shoot some slick sand or similar.

    Thank you for your ideas.
    I will look into buying a quart or gallon of primer filler.

    I'd recommend using a quart of Slick Sand because it doesn't shrink in later and will look good for a long time as long as it's sanded properly however you would need a spray gun with a 1.8 or larger fluid nozzle.
