The best exterior paint i jave found

[This review was collected as part of a promotion.] I was new to Gliddon exterior paints 8 years ago when i painted my new home. It weny on so nicely and in one coat. I still have not needed to touch up ANY of it, but each year i do a fade test to see how it is holding up. After 8 years in glaring sun, i have had very little detectable fading.

The inpatient person's paint!

[This review was collected as part of a promotion.] For those of us who don't have the [time, attention span, patience, energy, finances, help] that it seems like everyone you see with perfect, beautifully painted walls has... THIS IS THE PAINT YOU NEED!! Obviously, all those things make it easier, less stressful, but when you're an old-school DIYer that deserves beautiful, durable color in your life... this is THE ONE and only PAINT you'll ever need!!
