Paint that does not paint

We pray for a calm day so we could paint the outside of the house at little chief. The Lord bless us with a very calm warm day. After we got the window tape up and spent a little while getting the paint machine going. we were ready to go. We got the primer on with no problem then Brent want to go home but we had about an hour of sun light left. I talk him into painting the finial coat on the house. We thought it went fine. The next day we came back to find yellow streak where it run. We figure we just have to touch it up by hand. Brent accidently pour out some of the new bucket of out side paint we did not know how much we need so we had another bucket. We use the little bit we pour out to touch up the outside then went back to the first bucket. Brent call to me in other room something wrong with this paint. It will not paint over another thing. the bucket look the same but the fine print on the bottom one said paint base and the othe said white. Without the pigment it clear and does not dry very fast and turn yellow. We went back on Saturday and start up the paint machine and got the house painted white right the second time. The White look Good. Brent well be starting to replace the shingles on the rood next and I will be finish paint thing on the inside.
We got one little load of 15 bundle of shingles put in our car took out to the house. Brent feeling great because he was able to put all 15 bundle up on the roof. No bad for almost 60 year.
