I just applied the porcelain chip repair in my bathtub. Now, after it dries (perhaps a day or two), it will show as a blob. What is the best way to buff it down so it's smooth? Also, while on the subject, the bottom of my bathtub has become quite rough, due to a mat I kept there for a number of years. Is there any way to make it nice and slippery as the sides? Maybe with some enamel spray and buff?
Thanks in advance...
