The POR works great when applied properly. You have to make sure you get a good clean scuffed surface for the POR then scuff the POR for the UPol/Rhino/Linex. Never really had a problem with anything sticking to POR. But, if the surface is not clean and scuffed, I've had POR not stick. Done a few cruisers interiors this way. All holding up well.
How well is the Upol holding onto the POR as a base coat? I thought POR was not intended to be top coated, or at least nothing sticks very well to it. Curious to hear your thoughts. Super nice engine swap! Very well done.
