Nice job there. I've always had the opinion that if someone else can do it, I can too. I "can" do it, but some things I'm limited on because of time, space, or the cost of the tools to do the work. But mostly, why pay someone else when I can do it myself and save all those labor costs.
I think the reason some folks give so much "static", especially when it comes to painting, is because they've never tried to do anything themselves. They would rather pay someone than get their own hands dirty or spend the time.
In the end, you have a personal investment into the finished product you can be proud of. You know the value of your work and you appreciate it and that makes using it even more special.
I think you and your son did a nice job there! Looks very good.
So, just curious? Did you leave the temporary paint house up and convert it into a greenhouse?
