Is my steel frame trashed?

Hey All,

Looking for a bit of advice from the forum as am fairly stuck on next best steps on this one.

Bit of background, purchased a hand built steel frame in 2016 from a reputable frame maker. Have put around 3500 dry miles into it and the bike has always been stored inside. Frame was made with Columbus Zona tubing.

Was in the process of having the frame resprayed and the paint shop noticed small pin holes throughout the frame and welds which they think is the frame rusting all over from the inside and not worthwhile to repair as would involve essentially replacing all the tubes and relwelding.

Still awaiting a response from the original frame maker but in my opinion doesn't seem normal based on other steel frames i've had in the past.

Guess i'm after peoples opinions on.

• Is the frame ruined / repairable?
  
• Is it normal for a frame to corrode like this based on usage?
  
• Should this be covered under the frame builders "Lifetime Warranty"?
  
• Should I just accept i've got reasonable usage from the frame and let it go?
  
  

Have included images for reference.
