burn the door down why?
It is a little late to be asking if you have done this kind of damage to the present finish...you could have skip sanded the surface, applied a primer and repainted, the job would be finished, and you would have your Satin, matte, whatever finish you want.
If it isn't carved, you can scrape it with a piece of sharp glass. You will have to sand it afterwords, but it will be easier.
