Painting Aluminum boat

[Berdink]

Is it okay to wait a week after etching primer on bare aluminum to then do the bare metal primer?
I'm trying to follow the steps posted in these forums, but I don't remember if there was a maximum time frame between etching primer until the second step of bare metal primer.

I'll go back and see if I can find anything about this.
But I'm thinking I should be fine by just scuffing it with some light grit.
I'm going to go with the Rust-Oleum clean metal primer, and finally an oil based enamel.
.
I'll post back if I find the answer.

Sand, before priming wash with light acid wash, prime shortly thereafter, paint. I used brush/ roller on aluminum Feathercraft using Total Boat bottom and topside paint. Came out wonderful. use good masking tape for metal finishes that are not a polished finish.

Auto paint stores make a primer -etcher. Make sure topcoat is urethane 2-part paint(color and hardener) . If using etcher alone, read instructions on can.
