I have a wooden garage door that I'd like to paint. It has been painted before, and the old paint had been chipping and flaking off.
I scraped off as much of the old paint that I could, and then I sanded with medium grit, and finally washed the area with a high-pressure hose and let it dry. After I did this, there are areas where the wood is exposed, but around them is the original paint.
Then I painted my new coat, but the areas where the chips were scraped off are still very apparent. The area around those chipped areas is much higher and it looks bad.
Should I put more coats on, or will that not smooth it out? If not, should I try some kind of filler, or do I have to sand all the old paint off so that it will have a nice, smooth finish?
