It's easy to sand through the clear using #2000. Especially around an edge. To test if you've sanded through the clear layer, rub some white colored polish on a white cloth to the area in question, if you sanded through the clear the color of the color or base coat will show up on the cloth.
You have two options for sanding: you can start with the courser grit sandpaper (between 600-800 grit), or you can go straight to the fine-grit sandpaper (between 1,200-2,000 grit). Tip: For optimum results, you will want to start with a courser grit, and finish with the fine grit.
What is 2000-grit sandpaper used for? Finer sandpaper above the 400-grit mark is only used to lightly clean up or polish surfaces with scratches or streak marks.
Tack Cloths: Use tack cloths to remove dust and debris from the surface before applying 2K Clear Coat. These sticky cloths are highly effective in ensuring a clean surface. Sanding Materials: Stock up on various grits of sandpaper (800 to 2000 grit) for surface preparation and wet sanding between coats.
Anything can go through clear coat. It's a matter of how long it takes. 3000 is very light when it comes to sand papers... but you could go through clear using a compound, and a compound has a lot less cut than 3000 grit...

UV radiation: The sun causes slow, cumulative damage to clear coat over years by heating up layers of paint and causing them to separate.
Typically, this happens because the body panels of your car expand and contract ever-so-slightly in hot and cold temperatures. Eventually, after this happens over and over again, year after year, the clear coat loses some of its elasticity and starts to craze and crack.
Clear-Coat - The final clear-coat layer is what tops off your car's paint, so you'll need to be careful about the grittiness of the sandpaper of your choice. 1,500 grit is a good starting point, though you'll need to be cautious about sanding it off too much.
28-30 PSI spray pressure. Mix 2k Clear Coat with 2k Hardener and 2k Reducer to the recommended ratio. Strain thinned paint using a Paper Paint Strainer before use. If necessary, use a Tack Rag to wipe surface gently prior to spraying to remove any dust.
1000-grit and 2000-grit sandpaper – 1000-grit and 2000-grit sandpaper are types of automotive sandpaper that are used in the process of removing scratches and imperfections from a car's paint. The grit number refers to the coarseness of the sandpaper, with higher numbers indicating finer grits that are less abrasive.
First, wet sand with low grit sandpaper that can be used both wet and dry. Then apply rubbing compound to the coat. Next, wipe away excess clear glaze with a microfiber cloth. This process gets rid of any imperfections and makes the coat look new again.
2000 grit sandpaper is used for ultra-fine sanding and polishing tasks. It's ideal for achieving a smooth, mirror-like finish on surfaces like automotive paint, varnish, or lacquer.
Car-Rep 2K Primers
Clean the surface with a pre paint cleaner, such as degreaser (No thinners or acetone). For previously painted surfaces, make sure the previous layer is fully cured before overpainting if not advised otherwise. Sanding instructions: After curing overnight or 20 min @ 70 °C (158 °F).
Double Coat: Most automotive professionals recommend applying at least two coats of 2K clear for optimal protection and a good level of gloss. This is considered a standard practice. Additional Coats: If you're seeking an exceptionally glossy finish or extra protection, you can apply three or more coats.
Clear Coat
Just like with the base coat, sanding between coats of the clear coat is not recommended. If there is some imperfection or defects, then sand it down very, very carefully. This is owing to how thin the clear coat is.
Avoiding excess clearcoat
Some parts are particularly sensitive to excess product, such as vertical parts (flaps, doors, etc.), which may result in possible paint defects, such as sagging clearcoat.
The longevity of a 2K clear coat typically ranges from 5 to 10 years, depending on factors such as environmental conditions, exposure to UV rays, and maintenance practices. Regular care, including washing and waxing, can help extend its lifespan.
2K clear coat is generally considered worth it for its durability, chemical resistance, and superior finish compared to 1K clear coats. It provides a professional-grade, long-lasting shine that is particularly beneficial for automotive and other high-wear applications.
It is important to apply the clearcoat within 8 hours of the basecoat colour. It is important not to mark or sand the basecoat colour. 2K Clearcoat/lacquers will require the use of activators/hardeners (contains poly isocynate).
Rubbing alcohol will only damage the clear coat if it's used in high concentrations and large quantities. The clear coat is a protective layer that shields your car's paint from UV rays, scratches, and elements.
One of the easiest ways to fix clear coat peeling is with a clear coat repair kit. These kits typically include sandpaper, a primer, and a clear coat finish. They're sprayed on using a paint applicator gun and compressed air. Then, when the clear coat has dried and cured, it can be blended into the rest of the finish.
Beginning clearcoat failure is where the clearcoat is going to start looking faded, opaque and whitish. The next thing after the "appearance" charges is it starts flaking off like the paint has a rash.
