Engine coatings?

Post by GWCox »



I am pulling a 1978 GL1000 out of storage after being there for more than 15 years. In looking into cleaning up the engine exterior I am wondering if any of the engine parts were originally coated in any way, i.e. clear coat, plastic, etc. for looks and/or protection. I don't want to use the wrong cleaning materials or methods so want to know if I am dealing with basically bare metal or something else.

A lot of polished parts had a clear coat on them. That has usually yellowed if it remains at all. Not sure about that model, but other Hondas of that vintage could also have a silver paint finish on some parts. My guess is this was only done on cast pieces that did not meet QC as some bikes have it and some don't.

The engine is painted. The valve covers, belt covers, carb tops, intake runners, and forks will have had a clear coat at one time.

I dressed up my motor by buffing up the various polished parts as listed above. I started by removing the clear coat with paint stripper (follow it's instructions). After clean up, I then used 0000 steel wool as a first step to buff, then used a good metal polish. If there is any pitting, start with a more coarse grade of steel wool or sand paper and gradually go finer and finer. When all done I just used a good wax or detailing polish to protect it. I myself wouldn't even try to paint with clear coat because the surface would be too smooth for the paint to adhere. I don't mind redoing it once or twice a year.

Thanks to all who have responded. At this point I am basically cleaning up for the best look without a complete engine restoration. Then to loosen everything up and get it running.

I forgot to mention that I did the above polishing with everything in place. No disassembly.
