Hi, I installed 3 fence panels in concrete posts about a month ago. I didn't paint them with preservative however after being told that I wouldn't have to for awhile. Now it is time, but I don't want to use a paint brush and take forever. Can I use a bucket of B&Q preservative with an electric spray gun. Or do I need to buy a bucket that's marked for use with a spray gun.
Thanks, bhads.
