Anyone have a good source? Preferably free shipping.....online, obviously.

Try Amazon?

Yes, minimum order for free shipping and no place carries both clear AND yellow or red or anything else by the same vendor. Hate to pay shipping on each can. Better off going to Pep Boys.....

I saw both clear and yellow on amazon but they were both caliper paint I think. I also think you can try Amazon Prime for free for a limited time and shipping is free if you use "prime".
