Is it feasible to wipe the metal surface with banana oil and then spray plastic? Will plastic powder fall off easily?

The quality gap in banana oil is huge, and the price difference is even several times. If you use good quality banana oil, there is no problem. After volatilization, it has no corrosive effect on metals and no residue, and it will be stronger after plastic spraying. If inferior banana oil is used, it will leave powder that is hard to be seen by naked eyes after volatilization, which has a great influence on the quality of plastic spraying.
