Prime and paint without sanding or stripping?

Is it possible NOT to sand or strip a previously wood stained surface, apply a good quality primer and one or two coats of paint and still achieve a reasonably good finish?


I’ve five doors that over the years have had five coats of mahogany wood stain applied.


Two coats were applied 18 years ago, and 3 coats were applied recently.


Due to bad workmanship wood stain dark patches from the first two coats show through the latest 3 coats.


I considered sanding down the doors and applying fresh coats of wood stain.


However, on tackling the first door, parts of the previous coats of wood stain started to peel off in a form that resembles cellophane. Possibly this is because the wood stain is water based.


I abandoned the sanding and began to remove the wood stain with a scraper. This took two hours to complete one side of one door.


I then tackled another door with stripper. But this only marginally cut the time in removing the wood stain.


I considered a heat gun, but an article on Google said that this would turn the wood stain to a glue-like substance.


I’m sick of wood stain and would like to go for brown paint.


So would it be feasible to skip sanding/stripping, apply a good quality primer and one or two coats of paint? Would this conceal the wood stain dark patches and achieve a reasonably good finish?

 

Zinsser Cover Stain Primer & Sealer seems to be cheaper and well recommended. Is there any difference between this product and the product that you recommend?
