My boat is well over due for a clean. What is the most recommended /best brand of wax for the hull. And my interior. The sun pad almost looks dull. Thanks in advance.

Do a search in fiberglass and paint, many points of view to choose from.
Also depends on gel cote or paint.

I used Zaino on my boat. I also use it on my daily vehicle and muscle car. They have a full line of waxes and leather/ vinyl cleaner and conditioner. Best stuff IMO.
