Yes the small posts had a sharp edge to the bottom which caused cutting thru the clear coat,
BUT the CLEAR COATING is the main cause of the problem! all other excuses used for bubbling etc around the posts is just plane Bullshit.
Either Mirco is using a cheaper product now, or not enough hardener added to the 2 pack mix.
Sorry for Jack JJP, but he himself must work this out with Mirco as it's only going to bite him in the butt in the long run.
