## Questions & Answers

**Q: Will this epoxy work  on plastic fuel tanks?**
A: Yes, absolutely. We've used it on pressurized fuel tanks too. Fixed punctures, even cracked threaded connection collars. This is the best epoxy we've ever seen. The key is all in the prep work, using 80 grit as instructed. Once the plastic is sanded and prepped, for added strength it advises "curing" the plastic before applying epoxy by heating that sanded plastic area with a torch (flame). Clearly this step can be dangerous, do only if it's an empty aired out tank. Otherwise skip this step. Prep, prep, prep is the key.

**Q: does it work with wood?**
A: Yes, but the regular epoxy works very well with wood and is less expensive.  I bonded plastic to wood with this.

**Q: Will this epoxy work on cement steps**
A: Not sure how you're proposing to use it exactly, but it's a great product and will work on virtually anything.

**Q: What type of prep work is needed if i'm using this on a scepter water jug? light sanding? i'm trying to glue an abs 6x12" plate to it the jug.**
A: Sanding for "Tooth" and then a "Degreasing " on Both Items (jug & base) I use denatured alcohol.  I'd  lay the Jug Base down into the Gflex and let simple gravity do the joining. Hope this helps
