The panel must not reach a temperature above 194°F/90°C.

Use suitable respiratory protection (the use of fresh air supply respirator recommended).

Polish: Dust and minor imperfections can be polished out after the stated air-dry times have been reached, or after a full bake at 60°C object temperature, followed by a cool down of the object to ambient temperature. Before polishing, make sure the surface is well cured.

Follow the instructions of the polish manufacture.
