Lol, not the spam folder...

I haven't opened my shipment yet and just sanded the first window in prep for painting. Had to do a couple epoxy repairs and fixing some compromised window glazing before I will be testing out linseed oil paint for the first time. I have high hopes for this product - will provide another review post paint job and again after a year suffering Michigan weather.

Great paint. Better service.

As a sign painter reverting to LSO paint, Travis has been incredibly helpful figuring out technical issues of an old form of the trade. And of all of the LSO paints I use. Heron’s are my favorite.
