Had a bumper painted by Parker's, on my used '06 Altima, because the whole thing began peeling badly (assume from a previous repair) less than a month after I bought it. Parker's did an excellent job. It was completed when they said it would be and their estimate was very reasonable. (It was considerably less than I'd been quoted from a shop the Nissan dealership sent me to originally -that estimate was outrageously high).
It's been 2 years since it was done and absolutely no paint problems with the bumper. I will certainly use them again. Good people, good work and I highly recommend them.
