Scratches and cigarette burns on tubs are an unsightly nuisance. Fortunately they are fairly easy to repair with a few materials obtained from hardware and automotive stores. Heavier cigarette burns can be treated with a commercial repair kit consisting of liquid acrylic in combination with a liquid catalyst. These kits are sold by tub and spa manufacturers and at home improvement stores.

Clean the area with a soft cloth and mild soap.
Polish the entire area with automotive polish. This will help to return it to its original shiny finish.
Treating Heavy Cigarette Burns
Mix together the components of your repair kit according to the manufacturer's instructions. You will have to combine acrylic syrup, pigmented specifically for the color of your tub, with a liquid catalyst.
Apply the syrup in your repair kit to the surface of the burns. Follow manufacturer's directions as to the amount of time to leave the syrup on the burns.
Sand with 800-grit sandpaper, to remove the excess syrup and much of the cigarette burn marks. Follow up by sanding with 1200-grit sandpaper.
Clean the sanded area with a soft cloth and mild soap, to remove the sandpaper residue. Apply automotive polish to the area to help return the finish of the tub to its original state.
