Well I did not expect so much grumpy attitude from people who are supposed to be professionals. Well, first off what I meant by a temporary door is I work alone and it is much easier for me to take door off. Also it is easier to work on. So I sometimes have to cover the area with plastic. About the coating, the customer I am working for now (A builder )suggested that might increase the durability.
Sounded plausible to me. I work in a very affluent area, I don't know what housing projects some of you work on but my customers are very anal and they tend to be older which makes them set in there ways. I am not sure why I am even wasting my time to explain. Any way thanks for your phucked up support it meant so much.
Before you write us off, lets sit back in that chair and breath nice long breathes. ........Ok?, good. Now, please listen. Your response is very much like many that post on here with very general and vague questions. Stick around, you will notice too!

Do you realize that you are asking very basic questions concerning door refinishing? Of course you do.
Things you said in your OP shed light on your experience and background, or lack of them. The whole "flat" paint thing.
If I may be so bold, I would guess you have minimal painting experience. This is not bad, unless of course you paint unsupervised. Its like leaving a child around a shop with dangerous saws and such by itself. Not a good idea.
Before you jet off or stew about the aholes here all day (please don't ruin your day about something you saw on the internet, although I saw a video about turdburgers last night and was hard to get a goodnight sleep) could you please explain what your background is and what you were hoping to gain from this post?
I want to learn more about you and your business. How do you get these jobs from these rich old people? Do you charge by the hour?
Anyways, please don't judge us too harshly. I ask for your patience and understanding. We don't always deliver for new people. Please stick around if you didn't already delete your account.
