Im embarking on a project where im turning a model power transfer caboose into something worthwile. First, what type of trucks and knuckle couplers should i drop in, i dont have a picture but the car is marked with a "Saftey first" on the side of the flatcar part and an 8200 on the coup, If anyone has any idea what im talking about please give me some advice on what trucks and couplers to drop in there. Next, I tore the out of scale tool boxes and the coup off and its left a nasty residue, will goo-gone solve my troubles? Theres also some strange marker writing on one side of the coup, any ideas on how to get rid of that? And last: This caboose will be a peice of MOW eqiupment my RR got second hand from the PRR (I dont know if PRR ever used these things but hey, modelers licence damnit!) and they converted into a "jack of all trades hack" they use it for a caboose, a storage place for odds and ends during MOW duty, and a weed sprayer in the spring time. This thing has seen its fare share of dirt and grime, will weathering chalk sealed up with some dullcoat be good for this? Im not into painting on weathering because im horrible with a paint brush and most of my paint jobs are simple 2 color mask jobs with my airbrush. Are there any other simple weathering tools out there? Thanks for your time.
