Hello all
the problem is one of my customers has 2 yr old powder coated pvc windows,
they where sprayed with a protective coating for the building period (during the bad winter )
they are now ruined with marks that look like glue,
i,ve tryed a solvent cleaner which isn,t touching the test patch i tried.
they are talking about taking the windows out next spring to have them stripped back and re-coated so they are serious
amny suggestions
