SPI High build primer question

Ok here's what I've done so far on my '55 Chevy which I've owned since 1963. It's a 2 toned blue on blue Belair Hardtop.
In 1991 I had to shoot the roof and upper back end with Dupont lacquer and cleared it with 3 coats of lacquer clear. Well fast forward 20 years and many cracks started appearing. This summer I sanded all the silver lighter blue off doen to bare metal with some body filler still showing. Blocked it oretty well and shot 2 coats of SPI epoxy primer. Let it sit 8 days and blocked it lightly with 180.

Yesterday I mixed up my SPI HIGH BUILD PRIMER with about 10% reducer and shot my first coat. Using a 1.8 nozzle. Then about 1/2 way through not much material was coming out. THEN...It dawned on me...Instead of mixing it 4 to 1 with the activator, I had inadvertently mixed it 3 to one and it was drying pretty fast. Had to clean my gun out which took about 15 minutes or so. Then I mixed up another batch 4 to 1 and 25% reducer. I shot the trunk lid first as I wasn't able to shoot it the first time since the gun clogged up. Shot both upper quarters and it all layer down very nicely. In 5 minutes or so shot another coat. Here's my QUESTION...
Will it be OK having been mixed with too much activator in the first coat on roughly 60 percent of the area?? I plan on waiting a couple days before blocking it out.

Note: I haven't stripped the roof yet. Wanted to get the upper quarters and trunk done and primed first.
