did you have any problems with the plastic rails expanding in hot sun?

I was told a couple of years ago that any wood shop that does teak can do white plastic ... but am not sure of which white plastic is best ... king starboard in short lengths seems to be ok ?

I have an 8 ft piece of 3/4 in PVC that I'm going to put out in the sun tomorrow to see. if it makes sense, we'll investigate cutting it up for a J24 training boat replacement rail.

Did you allow for any expansion on the J24 rails?
