Paasche H for bottle spraying bodys. and for attaching to metalizers
Badger Krome for everything else
I quit trying to get one airbrush to do it all.... I rather have 2 that each do what they do very well.
I didn't care for trying to spray a body with a fine detail airbrush and small cup.
and both are easy to clean
I have seen the fusion plastic specific paints but don't see a need for me as I always prime the model first , so no need to have a paint formulated for plastic.
I may have to get a can to try tho,, never know
If covering major rework maybe so, but there shouldn't be a consistent need to have such a high build primer that block sands off, in sheets of powder for use on scale plastic models.containg fine engraving.
I typically use primer to help detect minute flaws and provide a good base for following colors.
