".... resistant to chipping .... " means that it can chip.  I don't
think we want bits of glass in the cooling system.  I'm with those who
say keep it clean, that is, change the coolant regularly.  That said,
I've not had a problem with the plastic pipes on my '91 Volkswagen
Vanagon GL Campmobile.  What again is the reason for replacing those
with stainless steel (other than the "cool" factor, which seems odd
since only the owner will know about them)?  My plastic ones have
certainly never leaked.  Of course, older models had steel pipes, which
probably corroded.
