I have used a blaster on tons of the parts for my car. If its something you can take off the car they make blasters that are inside a lit and vacuum sealed case. I have found that they work the best. There is really no clean-up and it makes it easy to change that material you are using if it gets too full of junk. With the type of blasters you guys are talking about clean up is A MESS!! But if the parts can't be removed from the car then disregard this.
