My son and I just painted a two story barn in Farmington Ct. The barn is big enough to hold four cars and has six dormers. It had been primed and was ready for a final coat. It did need some sanding and priming on the windows, but other than that all we had to do was cover the windows and spray. What do you think this was worth in Ct. I did for my inlaws for a favor and now they want to pay me for it.
