Hi, Mr. Paint,,,Everyone has their opinion ,,no sweat. But , I painted metal cabinets by hand and poly over them 10 years ago in a cabin I bought in Mich. They were that awful 70s green color. Painted them a light oak color to match the wood inside the cabin. They look great and never had any problems with them to date.
Secondly, I guess the way I figure this group is , if someone comes here looking for advice, they want to more or less save some $$$ and do it themselves.(I know , not everyone ) Why come here, if you want a pro to come in and do it, or hire someone for advice? If that's the case, call a reliable paint contractor from the get go. Just my thoughts when I post.
