Nice Product
I recently purchased an aluminum outdoor table and chairs at my local grocery for use in our winter home. The intent was for the table to do dual duty - outside on nice days at the pool, and inside in the dining room the rest of the time. The first time we served dinner on the table we learned that the table has a rather pronounced topography based on how it is constructed. The central area is depressed and has a hole for an umbrella, and there are sections near the short ends that are likewise depressed. This is not a defect but rather how the thing  is made. I purchased the Comfort Shield to try to smooth out the tabletop. Fortunately the product is much larger than needed - such that I was able to make both a full tabletop size sheet and smaller sheets to put onto/into each depressed section. The result is a greatly smoothed surface that feels good under a tablecloth. My metal, outdoor, el-cheapo table is now a (semi) respectable dining room table.
