Was very pleased with your product. This was the first run for me. It is the answer for the resurrection of vintage scatter guns. I used your steam pvc method. Did the prime cycle, carded, processed an other coat. I then did 2 ten minute steam cycles with carding at the end of each one. After the last carding 4/0 steel wool. Final buff was on cotton buffing wheel, oiled it down and this is the end results. I am located in Tampa and we had a temperature of around 74 degrees and about 40% humidity. Process started at 11:40 and by 4:30 was complete. I will send some photos of the completed gun when finished. Receiver is being hot blued.
This gun was in a very pitted state and all could not be removed but it will put it back in service for a very anxious grand daughter.
