You can do it in your drive way (if you have one) When I did it I covered all of the electircal connections, ac compressor, power steering, alternator, pretty much anything that could collect water and is electrical. And remember all you want to look good is the paint so just spray the paint not everything. I used simple green with cup and bucket, and toothbrush. The shit came out looking brand new, and my car is white and 14 years old so. If I was going to do it again I would use a tooth brush. Best of luck
