First off, welcome back!! second, can’t help much on the figures, other than telling you to try some other manufacter, DML models makes tons of figures, so Im sure you could find lots of at rest figures. Also, theres always resin, which in case you dont know is more expensive, but some people says it’s more detailed, and you can find a huuuge variety of figure poses. About the weather, ive learned a thing or two. The two types of weathering to me are “worn weathering” and “dirty weathering” Worn weathering o me is stuff like faded/chipped paint, scratches/rust and that kind of stuff, and "dirty weathering is stuff like mud/dust and stuff that isnt really permanent, but those are jsut my classifications for it. Hmmm, where to begin…theres so much to know about weathering. First for chipped paint, theres a few methods. First, you can prime your model in a rust color, or any color that you want the chips to look like. Next, lightly wet the model with a rag and sprinkle salt, in whatever size you want the chips, to the places where you want the chips. Finish painting the model, and then lightly brush the salt off, leaving “paint chips” in the primered color. Also, many people just freehand chips with a tiny bbrush, and yet more people use a graphite pencilo make it look like its worn through to bare metal. Another popular method for weathering is Washes. after putting on a basecoat, spray the model with something to protect the paint. Many people use Future Floor Wax sprayed through an airbrush. Next, thin some paint in whatever color you want the wash, most people use 9 part thinner to 1 part paint, and once the future dries, apply the wash all over the model. Once it dried, dip a Qtip (ear cleaner/cotton swab thingy) in paint thinner, and scrub away the wash where you dont want it, leaving it in the panel lines and around rivets and stuff to bring out detail. Most people use either black or a rust color, just remember to seal the basecoat, or THE WASH WILL DAMAGE THE PAINT. I wont go into detail on rust, because there are so many ways to do it. you can also drybrush. Put some metal colored paint on a stuff wide old brush, and brush 90% of it off on a piece of paper, then lightly drag the bristles oove the model, and they will deposit paint only on the highest parts, sich as on top of rivets, and look like worn away paint, but try this out before on your model. Next for dirty weathering…there are far too many methods to go into detail. For mud, you can make a mix of glue, and dirt and apply it to the model in places, or cover an old tooth brush in brown pain, and pull back the bristles and “flick” paint on to look like mud splatter. but again try this on paper before touching the model.
There are far too many methods to describe all, but these are a few. Try the search bar, or specific questions for better help. Hope to see some results, and hope this makes sens and helps, Ian
