Thanks to The Washington Post for making your experience with HIMG® Surface Repair Kits SHAREABLE.

"If you want to attempt the repair, you’ll find two types of fillers. Some are epoxy-based, while others consist of two-part acrylic mixtures or light-cure acrylic. Look for products that have numerous reviews and a high overall rating, and read through the negative reviews and deep into the descriptions and instructions to ensure you get a patch material that gives you the best chance of success.

For example, HIMG sells a light-cured, clear acrylic that gets good overall reviews on Amazon. By checking the manufacturer’s website, himgsurfacerepair.com, you can see that the company offers both the clear product ($28.49) and one with white tones for custom color-matching ($32.95). The company says these work well for repairing “chips, nicks and deep scratches,” but only by looking at the question-and-answer section of the website may you realize that crack repair is not on that list. There is even a warning that it won’t work on hairline cracks. And for deep scratches wider than a hairline, the company recommends avoiding the light-cure products and going with a self-cure acrylic with components that you would mix right before use. HIMG’s clear SCA adhesive ($19.50) is in that category."
