## Questions & Answers

**Q: Anyone use it to fill small hole in a pontoon?**
A: The question I would ask you is - how big is “small”? Marine-Tex will adhere to the aluminum great, but you can not thicken like you can epoxy resin to hold it in place over larger cracks or cavities.  I would feel comfortable using it to fill a hole up to 1/8 - 3/16”. It would work well for a larger emergency repair. For a hole of 3/8” or larger, if I didn’t have epoxy resin that I could thicken, I would lay a layer of fiberglass cloth over the hole, after applying Marine-Tex over an area larger than the cloth patch. After that cures, put a second coat of Marine-Tex over the cloth. You can easily sand the Marine-Tex to smooth it all out when done, but don’t sand through the fiberglass.

**Q: Is this pre-mixed?**
A: You simply mix the two ingredients together and it’s ready to use.

**Q: is it light gray or dark gray?**
A: It is a fairly light grey and it can be painted.

**Q: I’m repairing rock chips on the keel of a Black boat hull. Will this stuff be a close match in color?**
A: Short answer - no, it cures out grey. If it is a deep chip, Marine Tex could be used as a thickened epoxy, then covered with gel coat tinted to match boat.
