Paint On Tank Blistering

I have a T100 Matt black, 2019.

cleaning it today and have noticed that in several places there are blisters / bubbles under the paint. The worst area is near the seat.

I have searched on here but can only find similar issues with plastic tanks.

Dealer has asked me to take it in tomorrow for them to take a look.

Anyone had similar issues or ideas as to cause?

 

Surely fuel tank paint should resist fuel spills?

These look like blisters when you get water trapped under paint also - because it’s Matt and a pain to keep clean - it’s had a tank cover on almost from new so I don’t think a fuel spill would get down near the seat. The others, less obvious are just above the knee rubbers.

I am hoping it will be covered under warranty ?

 

Took it to the dealers today, Very helpful and understanding.
I should clarify that this was under a Triumph tank pad fitted from new. It had started to lift so I removed it intending to replace it with new adhesive pads. It peeled off very easily and found the blisters. It can’t conceivably be petrol, it’s been sealed.
Dealers have photographed it and will be recommending a replacement. Fingers crossed!

 

Hi yes it’s a Bagster but I had a pad put on when I ordered the bike. Sorry for the confusion.

 

Hi - Just an update on this. I took it to my supplying dealer on Saturday (Dave Deaths, Isle of Wight) and they processed a warranty claim. Got a call today (Tuesday) to tell me that the tank is already in. Booked in from Saturday with a courtesy bike if I need it!
Very impressed with the dealers and Triumph. Great service.
