I have vinyl kitchen cabinet doors, I have had these for about 10 years now and they have slowly over the years turned a little yellow. I have been told that I could remove the vinyl myself with a heat gun so that I can paint the doors a new white. Can you please tell me if this is true? I am retired and don’t have extra money to have the doors replaced. I would really appreciate any help you could give me. Thank you in advance for all your help.
