Used the OC on my garage and was about to put on my home. However lots of complaints that the little passages (like corrugated cardboard) clog up. (I will check my garage today to see if there is flow coming out - job was done 7 years ago.
Or should I just Use Cobra “Scotchbrite” and forget about it? NOTE: This was a topic 11 years ago, but a lot of new products since then.
Thanks in advance,
