ok thank you all,
sorry I paniced. But we are now priming and you know I kind of like the white lol. I did notice when I primed that had a few siding pieces buckle but I fixed them.
when we primed the one wall we noticed as we put extra coat on that the dark siding started lookin like the others.
And yes will have to lightly sand cause even though we had 2 coats of they yellow on when I put the first coat of primer on it fuzzed up, go figure.
