I think it takes more to gritblast the springs,
'normally' they don't touch them and leave springs and outside alone.
they would have to extra unscrew the platform to get the springs off and you would have to adjust them again on the car (cornerweigh).
now you get the springsetting back as they were, so don't need to adjust hight after refurbishment.
--> and yes, If I were Nitron I would have communicated differently

The wee collars are doing what they are supposed to do - keeping stone and road shrapnel out of the rose joint. Buy new ones if you must, but it will make zip all difference, and guess what, the new ones will look exactly like that in a year's time.
Springs are cheap. Paint is cheap. Wire brushes are cheap. Labour is expensive. Buy new springs, or spend your spare time tarting your springs up, or leave them alone (they still spring, and it'll be a couple of years before the spring is so corroded that there would be any significant change in performance). It's never going to be economical to pay anybody else to clean and paint old springs to make them look new.
The two good things about the nitrons are (a) the rose joints are protected by O-rings and collars and (b) the dampers are really good. The rest is neither here nor there, so don't worry about it!
