While you are waiting for your new P4P filter

If you have some old filters from your previous P3 or P4 laying around, take out the glass and use some gluey 3M/Scotch tape, cut a thin slice and apply it to the edge of the lens/filter and push it on, works like a charm.
Just remember, if you have a pola filter, look towards the sky with the sun in your back, rotate and mark the "top" if you want max contrast of the sky
