Recoloring the Seats

List:

I’m getting close to the time when I will recolor the seats from my 71 XJ6 for user in the 73. They are currently black. The new color is a gold.

My question is should I strip the current paint off the seats before applying the new color? These seats, which were black originally, were stripped once before in 1985 and then recolored, the same color with Surflex, with excellent results. There has been no cracking or flaking off of the color. The paint supplier suggested that I could simply apply the new color on top of the current color.

Has anyone applied the new color on top of the old and with what results?

Thanks
Lou
