I am using DFLF402 now, but the stuff under the NCP is actually DP90 (before the LF). I dont remmeber the number but the hardener I used with the first DP was the stuff you had to let activate for 30 minutes.
I really have not had any problems with DP with the exception of it lifting feather edged DP.
At this point I am not sure what I think about it as a sealer. I ordered a 1.2 tip for my gun and going to see how that shoots. Once cured and sanded it looks awesome.
The biggest thing I like about DP is putting it on bare metal and filler over it. Really seems to bite.
