We bought some pine tongue and groove to put on some walls for appearance.

The milling was crap, and these are feeling like siding because the groove is not on the same center as the tongue, so a ton of these are proud of the next by up to 3/64".

I've got a bunch installed and the missus just noticed and freaked. What would be the best way to get this stuff to be flat? Could I use a handheld power planer without mangling things? We are on a pretty tight deadline to get this done. The folks are coming to do the bathroom install next Wed. We've got to get this stuff installed and painted before that. So I've got evenings after work this week and then next weekend for the wood installation and at least 5 coats of paint (primer for resinous wood, 2 coats of primer, and 2 coats of paint).

Or is there a better way besides using the planer.

It doesn't have to be perfectly flat and smooth, but needs to be relatively flat and smooth.

Thanks.
