Do realize that you are using the most selective stripper that Dynaloy makes? This also means that it will be the least aggressive for coating removal. You will have to extend the time and or go to a more aggressive remover. Both Dynaloy and HumiSeal make such products. Be sure that the your customer will finda more aggressive material to be acceptable if you chose to go that route. The more aggressive cleaner can also remove desired marking, so be careful there and be sure to rinse very well, or you will have cleanliness related issues. Controls will be key to this process.
