[RP TownTalk] painting vinyl siding

[Alan Thompson and Sarah Wayland]

So we want to paint our vinyl siding, which is looking a bit worn  
after all these years (at least 15).

We've done a little research which has indicated that we shouldn't  
paint it any color that is darker than its current color (which is  
white). This is because vinyl is manufactured to withstand heat  
stress tailored to how much heat the vinyl will absorb (which depends  
on its color.) If you paint it darker, it absorbs more heat, and may  
well warp.  But our painter says that painting it a darker color  
shouldn't be a problem.

Has anyone had experience painting vinyl siding, and if so, do you  
have any recommendations for us?
