..& pre-treating w/turpentine really helps! i painted the tires on my '60 deville & works great, but took the last of a friends can &dont know the brand...?
e-bay! -rat rod tire paint- I believe is the brand or @least the key-words!
used my friend left-overs on my '60 deville ...love the results -no flake, yellowing, or cracking!!
turpentine a must for pre-cleaning/bonding!!
