Went to check the tin of touch up paint for my WARCO Economy Mill. Put in such a safe place as to be invisible!
With a machine of that age, a few scars are inevitable! You should see my lathe where 20 years of brushing off swarf have scoured the top coat away in places. But it still machines metal satisfactorily.
It is possible that the colour will differ from machine to machine, if the exact RAL number is not specified. I always think of it as "Industrial green" because that is what most machine tools are painted.
So a mill from one Chinese factory may differ in colour from a lathe from another factory. And maybe the same applies to lathes, or mills from different factories. (i e Rong Fu Industrial Green may not be the same as from Weiss.
Accepting some of the quality control issues that have been seen, the colour might even vary from batch to batch!
