I've been working with Interlux products on my seacraft. I'm using the primekote followed by the perfection. I had lots of issues with the primer too. I finally got decent results by just using the roller and not tipping. I thinned 25% initially (as recommended) and then rolled on. I added a couple of cap fulls of thinner to the pot as I went. I found that the primer went on very thin and it takes a couple of coats to build up a surface you can sand on a bit without burning through. Now I always roll on a coat, let it sit for 30 minutes or an hour and roll on another coat. This has worked pretty good for me. If I were starting out again I would probably roll on three maybe four coats to start with. You still end up with lots of orange peel and it takes at least 220 grit to knock it down. Sometimes I use 150 to start with. That primer is hard and a pain in the ass to sand. Hope this helps.

On a side note. I found that the perfection paint recommends thinning to a max 10%. I tried rolling and tipping and spraying and haven't achieved the results I want yet. Digging around on the internet I found the Interlux professional application guide. It stated thinning to a max 25-35% is required for spraying. That being said, its probably ok to thin the primer and/or paint more than the can states. I think thinning more would help some.
