I am going to be painting my office here in a couple of weeks and plan
on priming the walls before painting. I've been doing some painting
over the past couple of months, and have been using Kilz2 Primer for
Home Depot.

Tonight I had to make a Home Depot run and noticed that they have Kilz
Premium Primer, which costs $6 more / gallon. Reading the back there
was no mention at how Premium differed from regular, save the sticker
price. Is it worth it to drop the extra $6, or is that just $6 wasted?

Thanks!
