Cowling heat damage

[Bill3558]

Does anyone know a solution to the paint getting damaged from engine heat?  It there a heat reflective coating  or something that could be applied to the cowling interior?

Thanks for any ideas or suggestions.

I have some similar (but worse) issues on the other side of my cowl opposite the muffler.  I think it's a combination of heat and the cowl flexing when removed and reinstalled.

I think all you can really down is lightly sand and repaint, and maybe put some reflective heat tape on the inner surface to mitigate the heat a bit.   But then you're reflecting heat back at the engine, so that might require some testing to know if it's causing other issues.

I have some paint cracks all over my airplane (2007 CTSW)...I think the factory paint was applied rather thickly and doesn't flex enough with the rest of the airframe, though it could also just be UV damage.  I have a body guy who's a pilot and has painted a lot of airplanes, and he's going to fix it for me.  I'll probably have him do the cowlings first since they're relatively easy, then maybe spend the money to have all the little airframe paint cracks repaired over the winter.

Also have plenty of similar flex cracks. Cowling, wheel pants, I think thats just the nature of the type of plane.

The cowlings arent stiff, the flexing when putting it on and taking it off leads to this.

The glazing used to smooth out the surface before painting is brittle.
