Question about composite patch jobs before we had proper curing tools
Back when I was new, we did composite fixes with just resin and cloth, no fancy gear. I remember one time on a Cessna, I put a patch on a cracked fairing. I used a heat gun from the shop, but it wasn't even enough. The resin never cured right, it stayed kind of soft. A week later, the pilot reported a buzz from that area, and we found the patch had peeled halfway off. It was a close call, could have been bad if it came loose in flight. Now we have those big ovens that cook the parts just right, with timers and temp gauges. Makes me glad how much safer things are now, even if I miss the old hands-on way sometimes.
