This case result was an attempt at having a local powder coater paint a case several years ago and didn't come out very well as you can see from the defects in the paint and I never attempted it again on another case after that for this reason. The case is also warped a bit, but could definitely be bent back into shape if this bothers you as the case is made out of metal.
The powder coating is also rather thick, so that also keeps the two halves from fitting together perfectly, but it is useable as is. The black powder coating can be removed if desired with a paint stripper such as methyl-ethyl-ketone (MEK) and you may repaint or re-powder coat if desired.
I had eventually planned on re-restoring this myself, but just haven't found the time and would rather let it move onto someone else who does have the time for a restore.
