Sensenich Glass Prop touch-up?

Postby pappas » Sun Apr 11, 2021 9:31 am

I have a composite covered Sensenich cruise prop for the Aerovee Turbo. It has some peeling of the finish on the leading edge near the tips. I believe it is only a cosmetic issue but would like to restore it to near its original condition.

Has anyone else seen this? If yes, does anyone know the approved method to repair/refinish?
I can post pictures......if someone can explain how to do it on this forum. I have been unsuccessful so far.

Edit..maybe this link will work.

Looks like the paint rather than the actual underlying glass.

Sensenich would be the place I would start for two bits of information:

1. The finish coating they would use
2. An approved method of repair.

I agree. I sent Sensenich an email with pics yesterday, but it is the weekend so I thought I would ask here. I'm guessing someone has already received a response from Sensenich. I'll call them on Monday as well.

Don, at Sensenich, already responded to my email. Quick service for sure. Here is his response:

"You can touch it up with an enamel paint."

"See attached installation instructions. I refer you to page #4, item #6" Which refers to this wear as being normal.

The following item #7 on page #4, says to "touch up the edge wear with "spar varnish".

I asked Don about spar varnish and he said that the glass-covered props are finished in Sherman-Williams "Polane", a catalyzed polyurethane enamel paint. He did not specify satin, gloss, or any other sheen. It appears that the spar varnish is only for natural wood finished props.

I will make the repair with black enamel, paint the tips with the same red catalyzed enamel I used to paint the plane, Dyna-Vibe balance, and done!

Thanks for the responses.
