Review: Worked Great! - 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.
Review: Quality product - 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.

## Questions & Answers

**Q: Will this product go bad if it isn't all used within 24 hours after removing the seal?**
A: Not if you reseal it (remove and clean the nipple and put a nail or bolt in the tube opening) stick it in a ziplock and put it in the refrigerator. Take it out before next use and let it come up to room temperature or it will be very thick and hard to dispense.

**Q: Can this sealant be used to fill in grout between tiles in the shower? Is it hot waterproof?**
A: This a marine and Rv’s sealer  for vehicles that requires movement only,  not for shower.

**Q: Will this adhere a flap down on an (epmd) rubber pond liner? i don’t need it sealed i just want it to stay layer flat.**
A: It does say in the specs that it remains flexible, so it should work.  You might have to scuff up the surface a little to give it a little more 'tooth', but see if 3M has anymore information on their site for this product.  Have you considered using an adhesive specifically made for epdm?  EPDM is used on roofs, so an adhesive should be easily found.

**Q: Can you get this clear?**
A: Any color you want, as long as it's white
