Hi-Tech foam pads are 100% foam, but they perform slightly different from each other on the basis of how theyâre constructed. Under a microscope, foam pads look like a beeâs honeycomb, small uniformly shaped cells. The smaller the cells the more densely the construction, this type of foam pad would be considered less aggressive, thus it would be considered a finishing pad. The opposite effect takes place if the foam cells were larger, or less dense. No job is too big or to small; we have the right selection with quality to match.
