You can repair scratches on Fountainhead counter-tops by sanding them with wet sandpaper. Sand the scratches lightly so you do not sand away too much of the surface.
In order to remove the scratches and Haze on the plastic you must first wet sand using 1500 grit, then 2000 grit and lastly 2500 grit. Also use a soft block so the sanding is even. The wet sanding will remove all of the heavy scratches and the haziness. Each step of wet sanding will result in a smoother surface which will be easier to buff up. Once sanded the headlight plastic should be smooth and scuffed. You will then have to use a buffing wheel with a medium grit compound. This will bring the shine back to the plastic by removing the micro scratches created by the wet sanding. Once you have a nice shine you can throw a coat of wax on them and wipe them down with a micro fiber towel. I recommend calling a local car detailer or auto body shop. The usually charge around $125. Another option is buying new headlights.
Using a wet sanding machine for automotive refinishing projects offers several benefits. It helps to achieve a smoother finish by reducing the risk of scratches and swirl marks. The water used during wet sanding helps to keep the surface cool, preventing heat damage. Additionally, wet sanding can result in a cleaner work environment by reducing dust particles in the air.
Wet and dry paper is used for sanding acrylic to achieve a smooth surface. When used wet, it helps prevent the acrylic from clogging the abrasive material, resulting in a more even finish. Dry sanding can generate more heat and produce finer scratches, giving a polished effect when used with progressively finer grits.
Wet sanding may remove some glues in someconditions. However I've found dry sanding more effective with most adhesives. It depends very much on the exact 'glue' in use here.
Wet sanding involves using water to lubricate the sandpaper and reduce dust, resulting in a smoother finish. Dry sanding does not use water and can create more dust, but is often faster.

Sanding wet refers to sanding with water as a lubricant to reduce dust and clogging on the sandpaper, commonly used for finishing or smoothing surfaces. Sanding dry refers to sanding without water, allowing the dust to be airborne and typically used for initial sanding or when water may damage the material being sanded.
have you tried using an acid? you can also try sanding it with a fine grit sandpaper that is wet. may scratch the tiles though
Yes, but only if the joint cement is still wet.
You really could do either or neither. If your using an epoxy primer sanding is not necessary. If not you could wet or dry sand whichever you prefer. Wet sanding makes for a smoother texture finish and less dust of course.
