Hi everyone,i skin parts for automotive interiors with cf using the ec high temp epoxy resin,after the wrapping i wet the fabric with epoxy,after 24hours i sand with 120grit and after that add 2 layers of epoxy when the first is at tack free stage.
After that i put the parts in an oven and ramp the temp at 100celcius,after that i have too much amine blush,it can stick to my hand,is this normal?
Is there any chance  the epoxy to keep blushing under the 2k clearcoat and give me a yellowish pary?
I must wait more time to cure after the complete cycle at the oven?

In greece under a hot summer day i measure 85 celcious into the car,it became extremely hot and the other clear resins i used,made a heavy  print through,i post curedbthem but their tg was 60-70,so they became printed through.
I post cure thw ht resin at 95celsious so the parts stay glass reflection alla the time!
