I've had my 86 345 for a month. The outside hadn't been polished in a long time, so I started in. It's now clear to me that the clearcoat is gone from the roof and the top of the sides and also the vinyl stripe has been removed.
I've polished the roof and waxed it... or part of it. When I start down the sides, I hit the demarcation between the plasticoat and metal. I'm wondering if I should remove the clearcoat from the top of the sides, down to where the stripe was and leave the bottom alone, effectively making the unit three tone: polished, clearcoat and gray.
Also, it is unclear to me what is happening in the front (haven't tried the rear yet). Is this some other material? It doesn't seem to polish the same.
Some pix attached. Will take pix of front and rear.
