What paint should I use to paint front door? The paint would go on two surfaces: steel or aluminum (door) and frame (wood). The door appears to have been painted previously with Comex Flex Glow (Acrylic Enamel).
A colleague of mine was telling me that I should use “Sherwin Williams Emerald Urethane Trim Enamel” (https://www.sherwin-williams.com/ProductDisplay?storeId=10151&urlLangId=-1&productId=312501&urlRequestType=Base&langId=-1&catalogId=11051#data-sheet). I have painted my house and garage door with Sherwin Williams Emerald Siding Flat/Satin. I was planning to use the same paint Sherwin Williams Emerald Siding Satin to paint the door.
What is so special about Urethane? Why "Emerald Urethane Trim Enamel" would be better? Would I be able to use “Emerald Urethane Trim Enamel” on top of the Acrylic Enamel? Should I just continue with the paint I used for siding and garage door?
The world of paint is confusing... Thank you for the help!
