Review: excellent produit technique et de qualité. J'ai collé des ailerons de stabilisation sur des kayaks en plastique. La durée de la colle dans le tube après ouverture est de quelques jours et non de quelques heures comme indiqué
Review: I read most of the reviews on the 3M Fast Cure 4200 Sealant and was a little warry but after using the product, I am very pleased. Yes, it is not an easy flow product out of the included nozzle but it has to be designed that way or you would have material all over the place. I suggest as others have, do not try to have to small of a hole in the nozzle because it is difficult when using a smaller hole. I kept tightening the nozzle after each hole I filled on my boat and had no problems with it. The product skinned over quickly and cured totally within 24 hours. I suggest everyone, read the directions so they are not trying to use the product for an application it was not designed for. Great product and will use again if the need arises. Wish there was one size smaller because once it is opened, in 24 hours, it can no longer be used. I was filling small screw holes where I removed snap grommets in the floor of my boat and wanted to protect the area the screws had created. Sealed great and permanent till I want to pull it out or put screws back in.

## Questions & Answers

**Q: I'm looking for something to help wtih my boat.  The fitting attaching my bimi top is loose from the vibration.  Hoping this can help me seal it tight**
A: This is a great product, I used it to seal my fitting s on my sailboat. Not too sure it will act as a pure adhesive. If you have fasteners and this product together, this would be a good plan.

**Q: Is this available in black?**
A: Yes from 3m

**Q: Will 4200 stick to pvc, vinyl and abs plastics?**
A: as far as i know it will.  i have used it to patch holes underwater on marine vessels.

**Q: Will this adhere heat cable (snow melting) to a metal roof?**
A: Yes but not advisable to use on asphalt shingles in my opinion .

This sealant is excellent. Cure time gives plenty of work time while fast enough to get back on the water quickly. Being in a tube makes easy to dispense and spread. It stands up to weather and vibration great. The adhesion is great and has held strong not had a single drop of water get by. Cleanup is easy if you do it right away. Great value in sealants.
