Thinking about refinishing yourself? We strongly suggest you don't. Bathtub Refinishing or Reglazing is not a do-it-yourself project; it involves the use of strong chemicals and materials that are beyond the skill and ability for most homeowners and untrained users. DIY kits are limited in their strength, durability and way they are applied. Most often DIY refinishing jobs end up being redone by a professional with the additional cost of stripping the peeling finish. If these kits actually worked, there'd be no need for professional refinishers.
