Can I use zincrom primer with no topcoat?

[xltom]

It's almost done raining here in Oregon(I hope) and I'm getting ready to get started sealing and painting my 12ft aluminum seaking. I've decided to gluvit the inside and outside of the seams and rivets. I'm also considering a camo paintjob.

Can I use Napa zincrom #7222 without a topcoat? If it's the color on the cap(tan), it would work well in a camo pattern as is. I could also get moeller or mar pro zinc chromate primer in green and I'd have 2 of the 4 necessary colors taken care of..I'd only need to add brown and black...

This simplicity would also make future repairs easier.The only reasons I can think of not to try it is lead poisoning...or a less durable finish... What do you guys think?

EDIT: Maybe zincrom primer can't handle UV radiation?

Still hoping someone has an opinion here....

It's your boat do what you like, personally I think I would prime the entire boat with either color of the ZC and top coat with what-ever you like, as I don't think primer is durable enough and doubt you'd find the other colors you wish...it's only a couple more can's of each and that much more protection, which can never be a bad thing imo.

Thanks HSF, I wish I could leave the aluminum bare but the gluvit needs uv protection...I might just use silver or gray rustoleum in quarts so it looks like aluminum from a distance. I've seen this on many drift boats.

You still need to prime to use rustoleum

Yeah I know, I've had the primer, gluvit, and rustoleum sitting here for months....waiting for the rain to stop. I've just been rethinking my strategy since I decided to do the outside of the boat too. I'll need more of everything now(gluvit,primer,paint)....
