Experiment in refinishing turn signal reflectors

Before I found the old new stock turn signal, I got a pair of front turn signals that were complete, but were pretty weathered. I started searching on how to refurbish the reflective surface of the light cluster and found a couple of options. Unfortunately the only right way to do it is expensive and uses the same method of applying a thin metal film just as it was done during the manufacturing process. Some people suggest “chroming plastic” which is a little cheaper. Others suggest using two coats of Krylon high gloss black plastic paint as a base and then two coats of “brilliant” silver paint. So I tried that, and after letting the clusters air dry, I put them in a low temp drying oven for a few hours.


After Krylon High Gloss Black for plastic:

After Krylon Brilliant Metallic Silver paint:

I’m concerned at how well it will hold up, but we’ll see. It definitely is reflecting light better.

A closer look

The turn signal indicator lamps have deteriorated due to exposure to the sun, water and moss. They’re supposed to be reflective silver, but they’re bleached white and literally crumble when touched. This part is interchangeable with the 99 and 900 between 1977 – 1980 (I believe).

The same goes for the tail lamps, though the lamp housing is a little more intact. The lenses are compatible between 1977 and 1980. After 1980 they get a little larger.

But these aren’t really the major issues .. 🙂
