Do they sell coverall tire dressing spray?(Blue can)

I got mine at O’Reilly’s, never seen it in a Walmart.

Not the coverall brand in huge stock but I did see A can..

Yes I believe they do, although you'll want to call and ask your local Walmart store to make sure they have it in stock. If they don't I do know part stores are most likely to carry it, such as AutoZone and O'Reilly's Auto. Good luck!
