Ok - I'll try to address the issue.
Omni is PPGs lower grade system.
The experience I've had with Omni versus PPG, HOK is this: the omni (color here, not clear) was very 'thin' in color terms. To get it spread evenly and cover throroughly - we needed 6 coats! Normally I do three - but it depends. Even the smell of omni products makes my skin crawl.
I acutally prefer PPG over HOK (division of Valspar) - but I like some of HOKs colors better.
Primers should be interchangable - of course against manufacturers warnings. I have done much experimenting with differnt brands, layering them, mixing them directly, etc. - just basically trying to get the paint to fail - and found them to be very forgiving.... that said - follow the manufacturers directions - they spent millions in R/D to make the products work well.
If you move to PPG you should not have to switch primers. I like k-36 from PPg but others have other preferences.
Ease of use will not necessarily change - quality of outcome will though.....Just go get a bit of the same color in the high grade paint - and give it a shot. Get good coverage with the color - and shoot a med coat of clear (let it tack a few minutes) followed by a wet coat - MARTINSR may jump in here and give you better pointers....
