Sealer preference / confusion

Newbie here so hold on, am looking for the correct next step as all body work is done and I've applied 2 coats of SPI 2K primer and sanded to 600grit. Which sealer if any is preferred? This is a restoration, old mustang. I've read the tech sheet states SPI 2K doesn't need a sealer for this primer prior to painting. Is that for certain circumstances or am I good to paint BC now? Or, should it get the SPI Epoxy Primer reduced for sealer, or use the product actually called 2K Sealer? I'm just confused.
Also, would a black or gray sealer affect the color of a medium blue basecoat, likely PPG Shopline branded?
 
If you have epoxy, it's the best thing to use. The color of the epoxy will affect how many coats it takes to get apparent coverage. For this reason, I stock black and white epoxy and make my own grayshades. If you had black and white epoxy, and gave me the paint code, I could tell you the approximate ratio of black to white that would make a good grayshade for your application.
 
The paint code is PPG 12547 (caspian blue). Of course I don't have either shade on hand but will get to make my life easier. I do have a spare gallon of Summit Racing Epoxy grey that I could use but didn't think that would fly at this level of painting. Unless its good enough.
 
That color calls for 2 parts white to 1 part black. It's always best to test the base color on a jobber-supplied test panel beforehand to see how many coats it takes to get true coverage. The proper color sealer isn't a replacement for proper coverage, it's an insurance policy against areas which might accidentally get a little less coverage, those are less likely to show with the right sealer.
 
I just sprayed a 66 Mustang in Nightmist Blue this weekend (Also a newbie). I sealed with reduced black epoxy, and finished with UV clear. I sanded to 320p and did one coat epoxy reduced 20%. Also note, I did get a sample of shopline to spray out and it took 6 or 7 coats to covers. I ended up with wanda which was only a bit more expensive and covers great.

Good choice.:) Shopline is just re-badged Omni. Omni and Omni+ are really low end.

Some sealer generalities:
Urethane Sealer, faster dry time to recoat, shorter open window. Popular in collision repair, production type work.
Epoxy as a sealer, depending on reduction slower to slightly slower dry time to recoat. Longer open window.

Thanks for the new paint brand option Darrenw, did they Match the nightmist ? I'm in their MIXIT color program and dont see that they can pull a mix for anything older than the 90's. Not that I know how to use this thing properly.
 
So, they did have the nightmist color in their database and it was different then the shopline (Was difficult to find, don’t remember exactly what I searched. Not all are there and I think I used Wandabase HS MM in MIXIT). So I got a sample of the PPG (Delron I think, their top of the line) and I liked the way this looked (the Wanda looked in between the two) so I just had the Wanda color matched to the PPG and came out perfect. If I knew I was going to just color match I probably would have just went with Metalux since this is what my local SPI jobber carries and he is awesome.
 
Just found a Wanda dealer within an hr of me, so going that route for the Base. SPI for epoxy and clear.
