PAINT HELP
I'm buying Summit acrylic urethane paint. Manufacturer says a white sealer is needed to get uniform color. Is that necessary? I remember spraying lacquer and acrylic enamel paints over grey primer and paint alike. Is that no longer possible with the acrylic urethane paints?
Info is much needed. Thanks.

A lot of colors are calling for a gray or white sealer anymore. if you're after the exact color you bought or trying to match the color the seal coat can make a difference. if you're doing a full paint and you don't care if it's 100% accurate you don't need it.
The main reason is if the color is a little translucent you can get by with less paint if you have the right thing under it. I use a light gray primer and make sure it's solid coverage if I skip the seal coat.

I can't get Summit's recommended sealer in my state, so I want to use their white and come back with a red over that.

You could do that, but shooting a color coat over a color coat isn't as good as over primer for adhesion. do it while it's still green and it would be better I suppose.
I would just shoot a full coverage coat of light gray lacquer primer and 400 it to even everything out and give a final prep.

You my not see it inside but outside you may see a difference where the lighter & darker colors are under the top coat.
Also it would be best to use a light color primer / sealer under a light color.
Same goes for dark colors, use a dark primer / sealer, you then dont need as many top coats for coverage.

I use a sealer before the color coats on EVERY job. Not only does it give a uniform base for the topcoat but also seals EVERYTHING underneath as in old body work,different colors,aged paint,sanded edges and especially seals "sinking". That term is when the solvents (reducers) in the topcoat color, slightly saturate DOWN into lower paint & bodywork; as the majority of solvents mainly evaporate UP & OUT off the vehicle. 2K primers (primer with a catalyst/hardner) help a lot if no sealer used.
A gray sealer should work fine with the "red" you are spraying. Make sure you have enough paint for complete coverage.

Thanks for all the information, guys. When in doubt I go to the people who have been there, and that is you guys.
I may not be able to spray the truck right now. I have a construction project breathing down my neck and the wife and I need the truck to haul supplies. However, I don't want to leave the primer without paint for ...3 months, maybe. Is it possible to apply a sealer over the primer spots to keep it from rusting? Would that work? Thanks.

Well, it kind of depends on the type of primer you used. Straight lacquer primer (primer & lacquer reducer) is receptive to moisture if left uncovered / painted. So the rust possibilites are there. If a primer with hardner (2K) was used you would PROBABLY be o.k. Maybe purchase the sealer (with a catalyst / hardner) you are going to use later on this summer and do your primed spots. Cover / seal all areas to be painted with color in 3 months at that time. I think you be just fine with that approach.
