I shopped around before i bought my supplies and i could of saved like maybe 75-100 bucks by shopping online, but the info that i got from my local paint supply store was worth 10 times that much. They pretty much walked me through the whole process. Granted i had done my research and new a little bit but My car wouldnt look nearly as good as it does if it wasnt for the guys at my local paint supply store. I would honestly go local and use what they say.
