Sorry to be a pain MJ

Could you give me your opinion on this please.

I managed to get the fitting free from its bracket with a slight variation of what you suggested (thanks very much).

On the image below you will see what I noticed on the hard line once I could see it more clearly.

My gut feeling is telling me "bubbling = corrosion" underneath. Can this usually be cleaned up and Re-painted or am I gonna have to splice in a new section.

I realise this is a difficult question without you actually being able to see under the bubble, just wondering if your experience may say it usually goes one way or the other.

Cheers Frank
