bumper prep
i have to replace the front bumper on my 02z. i went out and purchased a new bumper cover from gm. i would like to take care of all the prep work myself, this way the bodyshop only has to paint it. so with that being said, i need some help with the prepping part.
1. do i wetsand the bumper?
2. what grit sandpaper should i use?
3. is there any special technique to doing this?
3. should i primer it myself with autozone stuff or let the shop do that?
thanks for all the help
