Prep for Behr Paint

[michigan4x4]

Tried searching and couldn't find specific answers.
What are you guys doing before you spray the Behr paint?

I have an M101a2 that was is in CARC and had some spots painted with House paint years ago. I want to give it a new paint job using Behr exterior that i plan on buying from Home depot. Thoughts on Prep? I'm not looking for a restoration quality paint job, just something that will freshen it up.

Also, I've read the stickies and there seems to be some conflicting info about what to tell the Home Depot clerk to mix up for 383 green. some say use the federal standard number, others say that late last year home depot moved to a web based system. Has anyone bought Behr from home depot recently and successfully mixed a correct 383 green?

What specific Behr paint should I use? Some have mentioned 4300, others Marquee, and still others suggest ultra premium or something along those lines.

Thanks

Water hose, dish soap, green scritch pads for prep. Powered wire brush for any rusty spots.

Does this apply to non CARC also?

No experience with other than carc. My best guess says yes. Maybe someone more knowledgeable will chime in.

Wear a dust mask you don't want to breath in CARC dust.
Above mentioned prep is all I do, clean it, rough it up and have fun.
I just had 383 green mixed a few days ago at Home Depo. The guy told me they had updated their computer system so they only have to put in Federal Code, 34094 is code I used.

All of the above. Do you have rust? That needs something to neutralize it, I use red primer. But I've found that red primer and Behr acrylic are a bit hydroscopic, thus can rust underneath. I spray those spots with a rattle can rustoleum camo....then Behr......by any means necessary, brush, roller, spray.

I like the Behr Ultra Premium and a bit of Flotrol. I don't like the Marque for the level of hand work I do, it's like hand applying pudding.
