I think there are about 37 layers of paint on them already.
Might it be easier just to get new door frames fitted?
I stripped the paint back on our stairway and then sanded so the new varnish looked lovely.
Took ages, wore out a heat gun and a sander and covered the whole house with dust.
I would pay someone else to do it or just replace them whilst you have "yet" another beer.
ps: you are going to be drunk before this end of this thread
But full of confidence to tackle the subject with the wife.
