How should I go about choosing a painter to paint my fiberglass door and trim?

I had an entry door installed and tried painting it myself and really messed it up in places. This door is a fiberglass door and I really want it to look nice so I am going to hire a painter. One of the painters said instead of sanding the door he would use a chemical that would take the paint off and then he would prime the door for painting before painting it again. Another painter said he would sand the door as much as possible and if I wanted him to, he would take the door off the hinges and spray paint it. Which would be the best way to go?? I have already gotten two estimates and both have been in the same ball park so I am just curious as to what this chemical is versus sanding it. And will the door look better painted the usual way or have it taken off the hinges and spray paint it?? Oh yeah one more thing, these doors were supposed to be already primed but the acrylic latex that I used can be peeled off in places so I am wondering if it was really primed at all.How should I go about choosing a painter to paint my fiberglass door and trim?
Hey hookie dookie, sand the door so you get the brush marks out, I wouldn't use a chemical of any kind to strip that door and the painter that said he'd take it off and spray that's the guy for you. You don't need to sand that door down to scratch just the imperfections you made buy painting it in the direct sun light, any of these fiberglass %26amp; steel doors you have to put a drying retardent in your paint like ';Flotrol'; so it doesn't dry too fast .

pick a paint specifically for fiberglass dont sand it, it will loose itsa fire retardance, making it illegal to have in use, therefore forcing you to buy another $300 door.
