I'm stripping the paint off our 75+ year old front door (appears to be red oak). There are surprisingly few layers of paint (I see only four) and all but one are coming off fairly easily with the heat gun. The original paint (which may be a primer [it's white]) is sticking like glue. Ten years ago I did a door of a similar age and used one of those chemical strippers with good result, but I've read too much at this point about carcinogens and would like to say away from that. I've tried a citrus stripper, which is helping, but it is really arduous and the door is getting pretty beaten up with the number of times I've sc****d it. I'm concerned about overdoing it with the heat gun, which has already scorched the door in more places than I'd like (I'm hoping that a good sanding with erase my overzealousness).
Any thoughts on alternative methods of removal? Any insight on whether a good respirator would be sufficient if I decide to go with the scary chemical stripper?
