To use our fiberglass rodding, first figure out if you need the carbon or white type based on your stone and project. For 2 - cm materials, go for the 1/4 - inch width carbon rodding, and for 3 - cm materials, choose the 3/8 - inch width. When unrolling the 328 - foot roll, do it carefully to avoid tangles. Make sure the surface of your stone is clean and dry before applying the rodding. As for maintenance, keep the rodding in a cool, dry place when not in use. Avoid exposing it to extreme heat or moisture as it can affect its strength. If you have any questions about which type to use, just look at the options provided and match them to your specific stone and shop needs.
