Bubbles in Vinyl Top

As with a self adhesive vinyl graphic, I would first try using a credit card edge to push the bubble to an edge if possible. If this isn't possible (to move the bubble) then I would use a pin to puncture the bubble and push the edges with a credit card toward the pinhole until it disappears. Then I would wax the entire top to give it some waterproofness again. When puncturing the bubble, try not to nick the paint underneath.

Good luck!
