I have seen this before . Usually due to contamination of the prepared surface before the paint is applied.(see the dirty blade thread about the evils of silicone polish) Occasionally it is due to incompatible paint chemistry but this should not be a problem with a new aircraft!
Is it just paint or is the gel coat blistered? I have also seen this happen and is again a production fault.
Covering paint with a canopy will not harm it if it is properly applied, however hot, wet or cold it is.
You imply it has not been resprayed so Robinson is responsible. I bet they try to blame you though.
