Seam sealer fail - help

Make sure you let the seam sealer outgas enough chemical from reaction to mixing before paint. I found out the hard way that Sem 39387 2 part took 3 days or more to completely outgas. on the second application I left it a week and the results were great. I pulled tape 1/2 hours after it skinned and it flowed "just" a tiny bit to make the edges look rounded instead of straight walled.
