Hi, Jennifer in MN. First a tip.start a new thread instead of posting under someone elses thread. This board moves so fast that you post can easily be left behind and not seen by many people.
Second, I, personally, will not use any methyl chloride based strippers. There are other products that work slower but much more safely. Citristrip and Peel Away are the ones that I usually suggest. You have one of 2 things going on. One possibility is that the paint is milk paint. This has a totally different chemistry than modern paints and only one product that is still produced will remove it. Check The Old Fashioned Milk Paint Company's site in the FAQ section for the source. The second possibility is that you are removing the stripper too soon. Citristrip can easily be left on for 24 hours and Peel Away for 48 hours with no problem unless you have small children in the house. Both of these companies have web sites (www.citristrip.com and www.peelaway.com) so check them for more info.
Stripping paint can and should be fun. There are worse jobs. Sanding drywall joints is one. If you use good products and make it fun it can be fun and the results are so rewarding.
