Paint Bubbles
When I bought my 2005 Vert the rear hatch did not have any small paint bubbles on it and that was two years ago.
Now (its outside 24/7) it is starting to get these small bubbles on the corners of the rear hatch. I am sure if it was still kept in the garage the rear deck would out gas as much and produce these small irregularities.
What's the best way to fix them(body shop fro repaint, pop with pin or razor blade)?
Thanks!

Is the car covered when it is outside now???
I can see the bubbles well and these bubbles are rather severe....in my opinion. I am guessing that they are located in an area that if you raised up this panel ...the bubbles would be above an open cavity of where the under structure is bonded.
It could be one of the panels where the chemical make-up of the SMC is off and they can do this in time. It is know to happen on Corvettes and also other GM cars with SMC panels and not uncommon.
If the SMC has been compromised due to moisture...stripping it down to bare SMC and re-painting is still NO guarantee that it will not come back. Simply because primer can only stick to a substrate that is in good condition.
I have been asked by many Corvette and new Camaro owners who have a problem with a panel or panels on their car... and the only way I know to fix it is to either replace the panel with new one and hope for the best that that new panel is good....or grind out the suspected bad areas and laminate in new material and then fill over it.

The bubbles are on the left edge of the hatch as your looking at the rear of the car.
Based on that - what do you think are my best options?
1. Replace
2. Repair and paint?
Thank you for you advice and help!

If you replace the panel with a used one or if you can find a new one...there is no way to know if it will do the same thing.
Repairing it is also the same deal...if you fix it...depending on how it is repaired ...it could come back or start in another area.
Repairing it may be the best option.
And these bubbles are not on any other area of the car at all...correct???

It is A 50/50 scenario.

Another possibility
It may be possible that IF this deck lid has been painted on after the factory paint job...it can be that paint job coming off and you still have the factory paint job under it in good condition.
I have seen this happen before...and it was due to when the part was painted..the paint shop did not even scuff the facotry paint and it bubbled up in time...much like what you are showing.
