Thank-you for your multiple replies and also the great advice. I appreciate it and will definitely follow your steps. I appreciate it.
My ZX bumper is in good nick, my car has never been hit and there are no gouges or tears, so the prep should be (hopefully) straight forward. The only real flaws to speak of are where the previous owner used a machine \ self-tapping screw to fasten the plate the bumper, and I would like to fill these two holes. Thanks for your advice on proceeding with tackling the job myself. I already removed the bumper and skin from the car so no R&R required.
Regarding my comment on the body shop owner being dishonest, I stand-by my comments. As a regular Joe Schmo with a (small) payecheck that I have to stretch to cover bills and have some $$ left on my hobby, I felt very "taken-advantage" of, I have had many many many cars painted from small areas to entire cars and I know the associated costs accordingly, and I have never ever been quoted $600 to paint a bumper ever. Some of these Body Shops have to realize that regular guys like me, simply cannot afford this and I felt insulted, I am not an insurance job where they can make $$ off the work. I would have preferred if he would have stated that they would not be interested.
What is your hourly rate...curious.
