Lets put the record straight well lets try!!!!!!!!!!!!!!
Acrylic over Enamel technically NO........................ it CAN REACT in certain instances but not in some
Enamel over Acrylic,cellulose Yes........................BUT have seen Plasticoat react on Acrylic Happened to me
Enamel over 2 pack Yes........................But providing the paint is old
Cellulose over Enamel NO NO NO.............Will cause a BIG mess
Cellulose or acrylic over household paint NO........................Don't even go there
Now I know and I can here you lot out there saying it works for me BUT it might not possibly work on others and would cause a fellow modeler so much time and money.
The BEST advice I can give anyone who is not sure about mixing and matching well DON'T it's not worth it stick to one make and one type of paint it's not worth the heartake,don't believe me then pm Tug Kenny and just ask him what happened when he did on one of his models.
If you are afraid of posting any question on painting in case you look the fool just pm me and I will try and help
