Frequently Asked Questions

AI
Yes, a heat gun is highly recommended to ensure the shrink tubing contracts fully and creates a watertight seal. While a lighter can work for small jobs, it often provides uneven heating.
Standard color coding typically indicates the wire gauge: red is generally for 22-18 AWG, blue for 16-14 AWG, and yellow for 12-10 AWG. Always check the kit specifications to confirm.
Look for 'marine grade' or 'waterproof' labels. Connectors with adhesive-lined heat shrink are specifically designed to block salt air and moisture from corroding the copper.
