Review on PNT Paint Grade Plugs for Enhanced SEO by Zane Myers

This is more expensive than just buying wooden dowels and using a flat saw. inch of plywood and figured it would save me the time of cutting out all the dowels. Unfortunately since it works with holes up to 1.5" it means they ended up being too long and I still had to cut each one with a saw. If you aren't using a 1.5" hole I would just buy dowels and save money.
