I used dupli-color, got it for $59 at Harbor Freight, Herculining was $89 everywhere around here and $30 is $30. Prep is everything so I ground out all the surface rust I could find and scrubbed the rest with a red scotch brite pad, the big areas I used a DA to take some of the labor out. I used a Schutz (spelling?) gun to spray it on so it looks just like a commercial job. It's an all day project, I started at 9 AM pulling seats and finished pulling off the tape and plastic 6:30 that night, but it was worth it, it looks great and I think will last a long time.
