Hi. I'm new to the forum. I have an old (30-40 year old)in-ground Buster Crabbe in-ground pool with steel walls and a vinyl liner. It is heated with a Raypak propane fueled heater and I have a Hayward sand filter and pump with an in-line chlorinator. It's about 16'x 32' and goes from 3 feet deep to 8 feet at its deepest. The is one floor main drain and one skimmer and one return. It has aluminum coping and I have been unable to find the plastic or rubber strips that fill the gaps between the pieces of coping. Any ideas for replacement or substitution?
