Epoxy over powder coating?

[ksungela]

Can I spray SPI epoxy over metal parts that have been powdercoated? The powdercoating is in good condition. Can I just sand with say 320, then epoxy, color coat, clearcoat?

you can, just always comes to SPI wanting the epoxy to start on bare metal because anything between the bare metal and epoxy is taking away from the properties they know make their product work. That is powder fails, makes the epoxy look bad.

Also, if the powder coat is done right you can just hand sand with 180 and spray.
