That’s my finger pointing to a blister. When painting in the sun, the paint dry’s fast on top while it still wet underneath. That can lead to puffy little air blisters. I’ve got a couple to fix.
I can imagine myself in the future as a one of those know it all old guys giving unwanted advice to a novice home restorer; “Hey young fella, you shouldn’t be painting in the sun like that, you’ll get paint blisters. Why I remember way back in 2007 when I was restoring a house on Cedar Bough and it was hotter than the dickens, blah, blah, blah…”.
