Our parts are double washed in IPA however an additional wash will remove any oils or contaminates that may have happened during the packing process

Most paints will work from rattle can, enamels and acrylics I use Vallejo Air paints for the display models. Usually I prime if the end color is yellow or white otherwise no priming is necessary. Light coats tend to work better to show all the details.

I find that CA type glues do a great job as well as general purpose adhesives like UHU. You can also use canopy type glues as well but it does require a longer set time.
