ive noticed that muzzle and fixed it up a bit, but it was too later, it was already painted

so i put a little glue insid the muzzle and held it htere with masking tape, its still drying right now but looks like it will correct it pretty well, i had the first crew member painted yester but messed up my wash to i tiped it in my future bottle and it sliped of my tweezers and fell into the bottle, and at 2 am, my parents would wake up if i go upstairs to get what i need to take it out, so i waitied till this morningand all the paint came off! hopefully the plastic is still intact, so we got ourselves a nice paint remover lol, so il be re-painting it and il have it done in a bout 2-3 days along with the second crew memeber, in total, this dio should have 9 figures with it
now, for the weathering i dont know what to do exactly, so can anyone help me out, the setting will take place on a sumemr road somewere in europe
