Always wear the appropriate PPE and work in a well ventilated environment. You should never apply any ceramic coating without the use of gloves. Coatings are not designed to come into contact with skin. It’s important to note that coatings can be absorbed into the skin directly, or indirectly through the microfibre towels one uses during the buffing stages. It’s a good rule to use gloves throughout your entire detailing process as this will also minimise the introduction of unwanted oils and dirt from hands to the paint surface.
Coatings can have a strong odour and smelling should be avoided. Work in a well ventilated area or wear an appropriate mask.
