Leading edge expansion/cooling makes little dents come and go

[cgzro]

I've had an annoying problem with my Pitts for a few years now. When the wings were rebuilt with stock Aluminum leading edges it started to create a small dent when it heated up. Sitting in the sun on a very hot day, the blue leading edge on one side top wing will occasionally go 'pop' and there will be a small dent, when it cools it goes away of course (and goes pop again). Its not serious really but its annoying and I'm wondering if there is any simple fix that does not involve removal refabric etc.
