Thank you for your question regarding the Delta Classic 400 - 60" x 30" Curved Bathtub and I am happy to assist you today.
Unfortunately, we do not carry repair or coloring kits, although we can recommend going through companies such as Multi Tech Products, who do carry such kits to make the repair.
You will need to find an acrylic repair kit with a high gloss white finish to correct the dent.
I hope this is helpful!
If we can assist you with anything else going forward, please do not hesitate to give us a call at 800-355-2721.
