Hi all:
Andy... best fix for this is sold at all plumbing supply houses I have ever been to... called
PORC-A-FILL and
PORC-A-FIX... SEE PICTURES BELOW. This works on all metal type tubs.
If chip is deep may want to use the filler first, let dry and then apply the porc-a-fix to finish. If real superficial chip then may only need the porc-a-fix. Read and follow all directions for best results. Repairs using this stuff are almost seamless... ;)
