It's been years since I chromed anything but from what I remember, the chrome will not fill any pits you may have. I think the chrome is only .002 thick back then. Also , when they chrome things its put in a large container therefore if you chrome 1 item or 20 its all about the container size they use. Again, this was about 30 years ago. Also prep work is key for cost as far as cleaning it up the best you can. My .02
