I built a small 6X8 tool shed, 8 feet at the peak. I have primed it and am now ready to fill the nail holes and finish paint it. I tried to fill the nail holes with caulk but for some reason they sucked in. These are finish nail holes. I just returned from HD where I asked the paint guy about filling them with window glazing. He didn't even know what glazing was. I left. I did a Google search for latex glazing because I would prefer not to wait a week after applying the oil based glazing before I paint. One hit on Google suggested latex glazing was messy, sticky and runny and he did not suggest using it for filling nail holes.
Any product suggestions would be appreciated.
