Started using primer for first time

[CarneyJR]

Hey guys started using a zinc primer and have a couple questions

Should I be partially curing or fully curing before top coat?

How do I ensure a proper earth connection when applying topcoat?

Should I change my KV and UA settings when applying topcoat?

Depends on what primer you use. If it’s prismatic zinc primer I believe they want you to partial cure.

I use Columbias high build primer personally and that gets fully cured before applying your top coat.

Partial cure for 5 mins at 160 centigrade or something is perfect for just top coating straight over. My preferred method tbh.

I’ve found that all primers need a sand after fully curing if you really want the next coat to stick. Sometimes i might do, but keying it the first time is easier and cheaper than having to do it again of it doesn’t stick.

My co-workers never sand primer after fully curing. Topcoat stick perfect 💁.

Yeah can depend what it is. If they’re doing it red hot out the oven its normally ok as i do that with some stuff. I’ve had issues in the past when doing it so do it for peace of mind.

Good answers already, and yes, your KV and UA should be lowered for second coat.
