First of all.... Welcome to the 405th!
You're pep dose indeed look great, keep it up
As far as preventing warp/disaster when resin coating:
1. Make sure to install the support struts inside the helmet.
2. Do NOT try and resin coat the helmet in 1 pass, this caused too much weight, and saturates too much of the overall piece, thus, causing warpage or explosion! (I dramatically stretch the truth!)
Slowly cover the whole helmet over 3-4 passes;
Coat 1. Start with say the bottom opening (going around the whole opening and up the helm for about 3 inches)
Coat 2. Do both sides of the helmet (stopping at the top of the face shield.
Coat 3. Do the front and back of the helmet (stopping at the same point as coat 3)
Coat 4. Do the top of the helmet... (and you're done)
You will have no warpage and have a smile
Now lather, rinse, repeat on the inside! (This time, do it all in 1 coat!)
Then... choose, Glass/Resin, rondo, or both!
Cheers,
Dave/Cereal.
