Review on 🚤 Superior Fast-Cure Sealant: 3M Marine Adhesive 5200 White (06520) by Ryan Carter

3M 5200 sealant is the best sealant money can buy. After trying many different products I've found this works great on van roof seams. Scrape off old sealant and apply 3M liberally. RV windows too - forget silicone sealant, use this 3M sealant and you'll never have to seal them again. In addition, it is available in brown, mahogany, black and white colors. Fast Healing is only available in white. Depending on the temperature and humidity, wait a few days for it to fully cure. A quick treatment takes half as long as a traditional treatment.
