I tried painting WWW's for my 52 Poncho. First thing I did was find a set of good used tires to deal with the new tire oil release problem. I also found a set of tires with a ridge where I wanted the Whites to be...ended up with about 3 1/2 inches...After taping off everything other than where I wanted the paint, I scuffed the surface and wiped it down with paint thinner and let dry. Repeated a couple more times. The paint that I used for the first coat was that Kilz stain blocker in an aerosol can. Actually did about 4 coats of this and then followed it up with about another 4 coats of semi gloss white Krylon. Recoating after each previous coat got tacky. Everything looked great when I was finished...until I took my car for a spin....2 blocks later, and everything was cracked. Very fine cracks mind you, but very white. After a while, I really didn't mind the cracked look...gave it that weathered look. They still look nicer than the original WWW that I have hanging in my garage. I'm sure there are better products out there, but cheaper is always better in my opinion...cost me about $30 and maybe 2 1/2 hours...
