Community colleges often have night time courses and weekend courses, meant for adults who work during the day / week. Look up your local community college and get a course listing from them.

Or, as was suggested, find a local body shop that is willing to bring you in on Saturday mornings or something. You may have to do **** jobs here and there, however the education and eventual experience is worth it.

Finally, my usual disclaimer to you - finish the schooling y u have to finish. High School is very important to you, as a stepping stone to the next level, whatever it may be. Instead of stocking parts to get an hour's instruction in a paint booth or applying bondo to someone's car, spend that time making sure you will graduate from High School. Play hockey, be social with friends, tinker with your car, finish school. Working part time is admirable, and should fill out whatever available time you have. If you can make money on the weekends working at a parts counter / warehouse stocker, you'll get exposed to a lot of automotive experience that can help you just as much as some unpaid exposure in someones shop. Right now, go for the money - you may need it for the Votech / University after High School.
