Seem wasn't too bad, can see through it cause of the clear epoxy and gap was about 1/16 thick. I have about 2 hours in body work and should finish it in about 1 more hour. Any advice from other modelers on the best radio box that works and looks good for the Thunderbolt? I purchased a fiberglass and CC Racing wooden box so far[&o]. Fiberglass box looks cheezy and wooden box is trick but too shallow. Please post a picture and dimensions with your response so I can see the advantages, I want this to be the last radio box I purchase.
