Sounds good but, ... pictures or it didn't happen.FWIW I just painted my whole car. I wanted to color match the valences at the same time. The first one I skimmed with glazing putty to remove the texture, but the texture is so fine on them that on the next one I tried just using 4 coats of high build primer. When it dries it will look like the texture is still there but a few minutes of wet sanding with 600 and they were smooth.
As others have said removing them is pretty simple, clean them very well then prep and paint, I had no issues at all and spent less than $100 to paint the whole car in single stage acrylic, granted its a cheaper paint but it looks good and it was affordable. Of course if you dont have the equipment to spray your own then that is an added cost.
