Bought a used '99 996 in September. Great condition and thrilled with the car but it has some very prominent 'bubbles' on the top of the leather dash. Under the bubbles the dash itself feels flat so there is no warping. I live in the Cayman Islands so it is hot every day of the year. The interesting thing is that at the end of the day the bubbles are completely gone and the leather is nice and tight. In the morning, when the dash is cool, the bubbles are back. As an experiment I used a hair dryer one morning and low and behold the bubbles eventually disappeared. Any suggestions on how to stop the bubbles from reappearing? I've seen a few posts about injecting glue into the bubbles with a syringe. I'm not an expert on leather but is there anything I can apply to the dash when it is nice and tight that will keep it that way. Thanks.

 

...do not inject glue into your leather dash bubbles...

They'll seek the path of least resistance an probably reappear elsewhere.

Use Connolly leather treatment on entire dash. May relax the bubbles.

One thing for certain... the treatment will not harm the leather. Glue possibly will.

Under the leather, there is foam. This is why injecting glue won't work. Glue will not spread out evenly.

The adhesive is loose and only sticks when car is heated. This is why you should always use sun shield and tint windows.
