Paint on 69 parking light

[Sixt8Chrgr]

I have overspray from an old paint job. Any ideas on how to remove this without damaging the light? I shot some stripper on it and it worked but I thought it was too aggressive and may melt the body of the light.

Is the inside of the light body in front of the lens an argent silver paint?

Thanks

Soak it in Castrol Super Clean for a few hours.
