First thing that comes to my mind is what I feel is the worst situation that a painter could face, when bidding or when beginning a new project. If this problem is not recognized before an estimate is made, then you are not going to be a happy painter, and your profits will be eaten up because of the extra time needed to fix this nightmare problem. The situation I speak of is whenever someone paints water base paint over oil base paint. Most situations this is a bad bad deal. The water base won't stick to the oil base paint and you can basically scrape the top coat of latex (water base) paint off of the underlying oil base paint with a fingernail. There is absolutely no quick fix for this. Sometimes you will get lucky and if you had sanded really good, then the latex just might stick to the oil well enough that it wont peel off everytime you look at it wrong. The only fix for this is to remove all the waterbase/latex paint from the top of the oil base paint. Basically, start over and prime with an oil base primer. Latex paint sticks to oil base primer no problem. If you use oil base primer, you can top coat with either latex/water base or oil base paints.
