Reduced Epoxy or non reduced before 2K

I have blocked my 3 coats of SPI epoxy with 180 and plan to do 1 coat of epoxy then 2 coats of SPI 2k. It's really nice and straight, so I plan to block with 400, then go over it with 600, then go with a reduced epoxy then base, then Universal Clear.
My question is can I go with reduced epoxy before the 2K, or should I go with unreduced epoxy under the 2K, and would the adhesion be better one way or the other. I am thinking the reduced epoxy will go on much smoother than unreduced for a nice base for the 2K, but don't want to do it if adhesion will be less than that of an unreduced epoxy.
It will be my daily driver truck, but since I like to play with this stuff, I am going to try to make it the best I can, including sanding the Universal and re coating with 2 more clear before final cut and buff.
Thanks in advance for your help
 
I am arriving at the place were I think the most durable foundation for a paint job is to start with 2 coats of epoxy, follow with 2k and block sanding sessions, then seal with reduced epoxy prior to paint.
 
You are a 100% right, the epoxy will totally chang the strength of the paint job.
 
Would you recommend epoxy between 2k sessions? If I have epoxy down on the bare metal and have been through 1 round of 2k blocking, and want another round of 2k after that, should I just go to 2k or put a coat of epoxy in between?
 
Thanks guys, I had this idea in my head that if the reduced epoxy would help with chip resistance prior to base maybe it would work well prior to 2k.
Glad I asked. Unreduced it is.
 
To take care of the 180 scratches. You thinking just go epoxy all he way? Perfect paint job says go with 2K but is all epoxy a better way?
 
If all you have to do is take care of 180 scratches, a coat of epoxy will definitely do that. What I usually do as the last step is 1 or 2 coats of epoxy, then block lightly with 220 until most of the shine is off of the epoxy (about 90% finished). Then sand the remaining 10% with 320. This is for non-metallic.
