Mike- I’m pretty sure it’s starting to degrade. I’ve posted a similar thread here (http://www.largescalecentral.com/forums/topic/22294/aml-track-ties-painting) and Andy has got the same issue.
Oh dear , that’s a bit ominous , that certainly seems to be collapse of the structure . I am surprised at its happening with 4 year old track .
Part of my previous job involved life tests of military equipment----if you knew how much your and my governments pay to test stuff to destruction you would be appalled----- however , the idea is to stop stuff failing when troops are in danger and so on . (I have a feeling tac was involved in that too) .
Anyway , the trick is to accelerate the environmental effects on equipment , and a lot of the data is passed on to industry where secrecy is not an issue . Where plastics come into this is when plastic is substituted for other more expensive materials----typically , mass produced weapon parts . So rather than having , say , a gun butt fail suddenly through exposure to sunlight , the stuff is tested to destruction and either lifed or discarded and new solutions found . Because the plastic industries are involved in these test results , they can read across to other projects . So it seems that the plastic track manufacturer did not take advantage of the life data . Or perhaps did , so that they got a regular replacement turnover (I am not saying that as a fact , but I do tend to get a bit cynical about some of these “unexpected” failures.)
Having said that , I have no concrete info to help you , but paint may well decelerate the decay----if you can get the automotive plastic spray as used for car bumpers(fenders) that may do the job . The problem there would be finding an appropriate colour .
I am really disappointed to hear of this problem , there really is no excuse for it given the data available .
PS I hate to have to say it but my Peco and LGB track do not suffer from the problem----yet .
Of course , according to some it’s because I have it surrounding my armchair and not laid out .
