Decal removel and restore
 

What is the best way to remove decals? If nobody answers I am thinking a sanding disk on angle grinder on the hood. Not sure on the fiberglass though on the dash of 147????

Heat gun on metal with a putty knife. Goo-Be-Gone also worked well for me after I got the decal started for removal.

Heat it up with a heat gun or hair dryer, then scrape it off with a razor blade. Use a plastic razor blade if you are worried about scratching the paint. Sometimes you can just get a corner started and peel the rest off by hand. There will probably be some glue left behind, there are adhesive removers available, but there are lots of other things you can use too, rubbing alcohol, acetone, lacquer thinner, WD-40, brake cleaner, etc. The harsher stuff may damage the paint, but it sounds like you are painting it anyway.

Use a heat gun to get a corner lifted enough with a plastic blade to get a hold with your fingers.
Then keep the heat applied to the opposite (underneath) side while SLOOOOOWLY pulling
the decal upward a a 90 degree angle.
