Shining up old Bakelite sideplates

I use the 303 protectant for everything, even my hypalon inflatable boat. Like the advertisement says "it's sp40 for your stuff". It shines and protects from future sun damage. A little goes a long way.

A little goes a long way.

Use it on a piece of sponge and keep that sponge in a zip lock bag for next time, amazing how long that one sponge can go.

if you spray it onto a cloth the cloth just soaks it up and you get very little out.

I'm going to have to get some 303 and try it.

I use S100, apply a light coat on the part, and buff it out, you can finish out with a nice car wax will really bring it out. Another technique is to try using one of those harbor freight buffing kits. Almost all of them have a rouge for plastic, that would work with that, once your buffing wheel is set up you can lightly (key word is lightly) run the side plate on the buffing wheel (drill or grinder mounted). it will take out light scratches, but don't try to get the deep ones you well actually take material away and cause it to be wavy like.

I hope that works for you.
