Engine Paint Touch-ups - What should I use?
« on: February 28, 2015, 10:39:23 pm »
Hi again C10 experts.

Sorry about the flurry of questions from a non-C10 owner (I used to have one)!  I am working on some maintenance items on my 1986 ZX900-A3 Ninja and while I am addressing those items, I wanted to touch up a handful of scratches and nicks on the engine.  Some parts appear to be powder-coated as the paint is very thick (crankcase, engine covers, etc.), while others appear to be normal black paint (cam cover, cyl head, etc). 

Wondering if there are some recommended paint types that blend well and could be used to touch up those nicks and scratches before I start putting things back together.

Thanks for any input and advice.

Me too.  I own a '01 C-10 whose right side crankcase has a few nicks that a black Sharpie cannot hide.  :-)

I'd like to know how to get a nice thick paint job to match.

Hey Matt!  Hope all is well (my son and I did the MSF training with you at the National in TN).

I am hopeful someone has found a thicker black paint that would blend well with the powder-coating.  Clean up the area well and a little work with a modelers brush seems like it would make it much less noticeable. I also have a few spots on the frame of the ZX900 that it seems would also look much better with a little touch up.

Hoping someone has found a good match for both the glossier powder-coated parts as well as those that are not so glossy.....

Guys, not sure if the paint can take the temperature, but...
You might try a paint pen with black paint.
If you'e not familiar with these, they are similar to a felt tip marker, but have paint instead of ink. They have metal balls inside, like a can of spray paint, that are used to mix the paint by shaking well while using.
They cover quite well and are very easy to use.
They are available in hardware stores and if you keep then tightly capped, can last years.

Never done it myself but Duplicolor makes black engine paint.  Just spray some onto the end of a q-tip to apply to small areas and do multiple applications to build it up.

And there I was thinking I was  the only one who did that....

I use regular black spray paint, the engine cases don't get that hot.

If you are that concerned, simply buy some black gloss/flat rustoleum hi heat paint.  Mix the two and test it to see if it is the right color/gloss.  In not, re-mix, try again.  When you apply, though, either use a paint brush OR cover the area with masking tape, exacto knife the pattern out and paint OR mask around the general area and simply wet/dry sand the overspray down to match.   No - not quick and easy, but works fine.

I use duplicolor engine paint "FORD SEMI GLOSS BLACK"  on the 7th gear bevel drive units I build. It's a very good match, color-wise. Steve

Thanks for the post, Soda.  I was wondering the same thing myself.  And, I was waiting for Steve to chime in so now I can go get the paint.  Thanks, SiSF!   :great:

Hi Jack!  Glad to read you and your son are still riding safe.

I picked up Dupli-color paint in a can yesterday.  Using a Q-Tip for a 'brush', I applied color to the housing.  You can see my results in the attached pictures.

Not sure who I will let close enough to check my brushstrokes but as you can see, from a short distance away, the results are satisfying.

Pretty much any satin black will do. It won't bake off (I painted an entire air-cooled engine years ago - it never flaked, never peeled).

I used the end of a can of the satin lack for plastic to touch up my engine side cases. You'd never know.
