Harley used to have a wrinkle that worked real well, too. May have been made by VHT too. Who knows. I have used the Harley and the VHT. Both worked fine. The hair dryer or heat gun is a good suggestion. That way you can get as much wrinkle as you want just by adding more heat.

I have VHT on mine now. When I get the chance, I think I will look into the powder coat. The rattle can wrinkle looks okay, but it just too soft. I have pulled some flat spots in the wrinkle around the oil filler with my fingernails.
