Ok so I have found a deck that is testing my nerves and patience. a 18x16 deck no spindles but a wrap around bench on the lowest railing that has a red solid (NOW PINK) BEHR. I applied HD80 at full strength dwell time of 30 minutes and it didn't even phase this crap! Some came off but left patches of areas that just are stubborn. So I tried letting the stripper dwell long for 45 minutes, and NOTHING! I am working on getting the booster for the HD80 as I was told it would help, But for now I have resorted to a Belt Sander with 50 grit then finishing it up with 80 grit. This is just the floor area and I had to call it quits today, any suggestions for the outside railings? I am a few nerves away from removing each board and Plaining them down 1/32nd of an inch to remove this. I've encountered stubborn behr before but NEVER like this! Anyone have suggestions
