I check the Fypon site and saw never special about painting it. Seems similar to all other PVC type products.

I would think also that some type of film or wax was on surface prior to first coat

Uhhh... isn't it very difficult to get good adhesion to PVC? I thought that PVC was almost unpaintable except for a select few things that could do the trick?

I just say this because I remember a supplier coming in and showing us a piece of pvc that he got some paint to adhere to and being pretty proud of it.

PVC trim can be painted under special requirements from the manufacturers.

We use PVC sill noses and brickmold for repairs and scuff and hit with 100% acrylic and have had no problems.

You washed them and the paint was coming off? were they painted at some other point in time by another paint contractor? if so was it there top coat that failed?

Fypon site says there PVC products do not have to be painted so I find it hard to believe that there top coat is failing.
