This is best described as a polish. It is applied with an angle-grinder and a cotton buffing wheel. Care must be used as you can burn or damage the glider.
"Hardwaxing" will remove small scratches and give it a beautiful shine. This product is used after a repair is done and is the final stage after sanding with 1500grit. This is also used by many once a year to continue the beautiful shine of the sailplane.
The heating of the surface that is done when applying the hardwax also helps soften the gelcoat surface forcing the wax into the surface and helps slows the process of crazing.
This is not a UV protectant.
