Before assembly, check the fit and remove the release agent with isopropyl alcohol or acetone. Cut off sprues with a saw/cutter. Wear a dust mask or respiratory mask when machining to avoid inhaling dust particles.
Carefully heat warped parts (e.g. with a hairdryer) and bend them into shape. Glue with 2K or superglue. Unpainted cast parts darken over time and can turn yellow - especially when exposed to UV light.
