I used a acrylic blending agent and it took forever to dry stayed sticky so I took some pearlex powders and brushed it over the sticky areas and it looked so cool. However I discovered much to my horror that if that blending agent isn’t mixed right and allowed to dry it causes the sealer to buckle and I was devistated! weeks and weeks of painting runined in moments. It couldn’t be fixed I had to strip the model and start all over.
I don’t know what to tell you but don’t seal it till it’s not sticky.
