Hi everyone,

Over the last few days I have been sanding my nasty outdrive to bare metal.
I was told by a boat dealer to use Moeller zinc primer and mercury phantom black enamel paint. My question is should I let the primer fully dry before painting the black? The reason I'm asking is the dealer said to spray the primer and before the primer dries paint it black. I don't want any issues because it was a lot of work sanding the outdrive and I don't want to do it again. So for those who have tackled this project can you please share what worked for you?
Thank you very much
Corey
 
I've only ever used Merc's primer and paint. I figure it's best to stick with the same manufacturer, but I have no doubt that other combos can work. That said, the directions on the Merc can clearly state to re-coat within a certain amount of time (maybe 4 hours?) otherwise you have to wait at least a week to re-coat. Re-coating can be multiple coats of primer or changing from primer to paint.

Are there any directions on the Moeller can? I would go by what the paint manufacturer states.
 
General rule of thumb, if the primer is fully dried you should scuff the surface up for a better grip for the top coat. Not necessary if the primer is still tacky or soft.
 
Hi Scoflaw,
That's what the dealer said paint when primer is tacky. The primer dries in 20 mins so I'm guessing topcoat around 10 mins or so. Thank you
 
When the primer has flashed {semi dried} put on your first coat of finish. Be sure to not to apply to much top coat at once let it flash also and apply in light coats until you have put on what you think is enough. Be sure to wipe down the outdrive with lacquer thinner before you paint to rid the surface of any oils or dust. Paint after the thinner is dry.
 
Yes to the zinc chromate primer and yes to hot coating it. You received good advice. Hopefully you used the correct sandpaper....
 
I don’t know the primer suggested, but since you are painting on old aluminum (not brand new), the primer should be self etching. I also don’t know your application. If it’s a trailer boat and you are looking for pretty, this will fit the bill.

If you are wet slipped, it completely misses the mark. In that case put a good self etching primer on first and then go to a good solid coating of Trilux
