I didn't do anything and I'm regretting it after only 60 hours. I'm getting a little bit of browning due to the exhaust heat and leaked oil seems to be soaking into the fiberglass. I've talked to several other owners with more hours who have encountered the same problem and once the cowling is oil soaked, nothing will stick to the inside despite vigorous cleaning attempts. Your idea of using thinned resin is not a bad one. I would weigh the resin and then decide if I wanted to do that or add paint (which is also heavy) or add an adhesive reflective barrier (some weight involved). One thing to consider is to use high temp resin to resist the exhaust temperatures. My #2 exhaust pipe was too close to the cowling and after landing from the initial flight (20 minutes) it had burned the glass and honeycomb (no exterior damage). I had to remove the burned portion and replace it with carbon fiber (for strength) and high temp resin. You have the same engine as me, so you may encounter the same problem. So, personally, I recommend you do the resin thing on the inside. But, if you don't want to buy high temp resin ($180/gal), then maybe use high temp light colored paint or self adhesive reflective barrier. Stan Sutterfield In the manual, Van's describes a procedure of mixing some resin 1:1 with acetone to form a thin coating for the OUTSIDE of the cowling to make a filler for the pin holes and other surface imperfections. Seems straightforward enough. But what about the INSIDE of the cowling? That open weave seems like its going to soak up any oil and whatnot that runs out of these leaky 'ol Lycomings. Thoughts?
