one of my main pieces was very flexible BUT had some flaking on it
i scraped all of the "dry" plastic of and rubbed it back ,in doing so lost all of the graining effect on a large portion of the panel
the restoration is relatively easy
i bought a product that is used to re establish the grain in a bumper bar after it has been repaired
wash panel with scouring pad till its all mat finish then plastic prime
4 coats of the bumper bar paint and it looks brand new again
not much point in naming brands as the aussie product will i am sure have a different name to the usa product
btw you need a compressor for this as it is not available in rattle cans
