Paint removal
« on: March 11, 2014, 05:45:15 AM »
I picked up a cb750 k3 basket case yesterday the frame of which has been painted brown over the factory paint. The frame is really good shape with vin tag being darn near perfect.  My question does anyone know of a way to gently remove the paint without damaging original finish? Maybe just better it PC?

Try rubbing it off with a rag with paint thinner on it.

IF you are careful, you can try wetting a rag with Acetone. Depending upon the type of paint used, the age of it, you may soften that layer up with soaking the original frame paint. This may allow you to "wipe" off the top layer.

Another option would be to VERY carefully sand the brown paint with ScothBrite pads. Try using green first.

Krud kutter makes some paint removal products that is good and safe. Take a hot saopy rag and let it set on the tank or side cover and see if it will lift or at least to try and scrape it with a finger nail. You'd be surprised what the person used for paint.

I'll look into that. The good is tank and side covers are stock and in good shape they weren't repainted

its going to be tough to get just the brown off.
the acetone wont discriminate.
Cheap and fast - scuff it with a scotchbrite pad, wipe it down, and repaint it.
More expensive, and time consuming (for you to tear down/rebuild everything) - send it to the powder coaters.
