65eTurbo Posted April 29, 2021 Report Share Posted April 29, 2021 Hi all. I'm encountering a strange phenomenon and I think it's likely isolated to my airplane but I thought I would check to see if anyone else has experienced it in case there's a common chemical on our airplanes that causes it. On an area of the belly on the pilot side near the back of the wing across the belly there are some splotches of paint that are soft and peeling and exposing the bare aluminum underneath. It's as though someone threw a handful of paint stripper onto the belly. I will clean and prep the areas and paint to match, but I was just curious if anyone else had experienced this phenomenon and figured out what chemical had caused it. The paint is about 35 years old and I've never experienced this before. Quote Link to comment Share on other sites More sharing options...

Bartman Posted April 29, 2021 Report Share Posted April 29, 2021 In my J that’s below the battery and also the brake reservoir. Not sure if this applies to you, or if the battery electrolytes or the hydraulic fluid would soften paint. Quote Link to comment Share on other sites More sharing options...
Guest Posted April 30, 2021 Report Share Posted April 30, 2021 The battery box vents are in that location. Open the fuselage side hatch and pull the battery out for inspection. Some warm water and baking soda applied should left you know if it’s battery acid spillage. Clarence Quote Link to comment Share on other sites More sharing options...
