This sub was a bobber tank car from a battery op. Wallmart train set. A model jeep sprue, 2-CO² pellet gun tanks, 2- magic marker ends for the prop cover/nozzles, 2-dollar store mini l.e.d. lamp arms, safty flint wheel from a bic lighter for a saw blade, Duco epoxy and a loose screw.... for the saw blade😬
Car is all fudgesicle sticks with bearing boxes stuck on.
Popsicle sticks simple wont work 😜
(etching primer green, enamel silver, craft acrylic yellow. If you put the silver on yellow/ bad reaction; put green on yellow/bad reaction; green on silver is ok if light,..... it's a matter of how "hot" paint is wet vs how strong the skinning pull is when the other is dy. Hot= penetration ability and usually also notes a flat laying paint, which often pulls hard sideway at the undercoat to/while it flattens/dries. That causes cracking, "gator skin"
