What kind of filler can be used for dents?
Our basic product line includes a part C powdered component which consists of 2 variations (one finer, and one coarser). This adds body to the spray coating which can either be trowel applied for small dents or other irregularities, or is generally thinned with lacquer thinner to apply using hopper gun as the bedliner.
The professional grade pure polyurea products are applied with Graco type proportioners or cartridge gun and cannot be modified as such. You would use normal body shop products or processes to prepare before applying these coatings.
