I stripped a couple of oak cabinet doors last summer. It was my first time stripping anything since I was a little kid helping my grandma refinish the really old solid oak dinning room table. So basically it was my first time. Since the stripper is pretty expensive I only used enough to cover the area, thought that would be enough. When I went to remove the stripper and finish it didn't do anything, had dried and didn't remove much finish at all. I thought maybe the stripper was some low powered junk and went and bought more and started a thread on here and did some google searching. Found that it was really my fault for not putting the stripper on heavier and it dried out while waiting for it to work. Basically wasting the stripper when I was trying to only use as much as needed and ended up having to use more. Spending dollars to save pennies. The second round I spread on pretty thick and added some more as needed when it looked like the first coat was drying out. I kept checking on it to see if the finish would come off when scrapped. When it did I scrapped it all off. Go buy a couple different plastic putty knifes, these are what I found worked best without causing damage to the work piece. I'm FAR from an expert but this is what I learned on my "first" stripping experience.
Thanks for your help
