My condolences. I feel your pain, and my prayers will be with you on your loss... The good thing is that you are O.K!!!... Better to have a scratched bag than a scratched hip or broken leg; there is no matching paint for those.
My advice as to painting plastics, take it to someone or a shop known for good attention to details, which also uses the right materials (paint, additive, & prep). The place where the actual painting is done should be as clean as possible (even a fruit fly will ruin a wet part, and last but not least fine sanding between coats will enhance the final outcome. Some places will actually paint better than factory specs. Do not use wax products for first three month after the painting is done, it will dull the shine. You should use 3M or any reputable paint non wax hand polish. Advanced AP, Napa, or PepBoys should have a few.
Looking forward to share a ride with you as I also live in the Atlanta area and have a Coors Light, I mean silver bullet (2003 FJR).
