Is the prep spray in the Delta kit or yellow x with the Dvelup kit neccessary? Does it work? Can you tell the difference if you don't use it?

I don't really see a difference if I don't use a cleaner. It just seems to remove some dirt and discoloration prior to sanding. After I finish sanding I use mineral spirits to clean the lens prior to applying the UV protection/clear coat.

It is imperative to use the restoration prep when restoring headlights. Below is a video so you can see the system in action.

Korey - What exactly does the prep spray do in the restoration process? The video doesn't show too much of the effect it has on the lens.

Thanks

One more question Korey, please. I see you guys now have a red Groits 3" polisher on your website. Is this better than the Metabo brand or does it serve a different function in the H/L restoration process?

Thanks

It is hard to determine what sanding grit to start with if you do not clean the lens first. Therefore, I recommend using the restoration prep because it cleans the impurities, grit, and grim so you do not sand them into lens prior to completing the headlight restoration. Also in my humble opinion, the red tool will suffice in a light to medium duty application but the Metabo is German built tool with a much higher quality so I recommend it for the headlight restoration professional.

Very nice....thanks for your prompt response.

No problem!

I bought my system from Dvelup before Delta Kits had the products available. In Dvelup's training cd they mention using Yellow X at the beginning of the process and at the end. The end seems to be very important because it preps and cleans the surface of the lens to receive the Clear Wipe. Without this final step, the UV protection will wear away much faster and that means the difference of offering a 1 year guarantee vs. a 2 year guarantee.

The prep / yellow x is just a cleaner. It is used afterward to remove any residue from the sanding and buffing process. I fail to see where this would double the warranty period. The clear must be applied to a clean and dry surface.
