Review: Nice - Works great
Review: Works easily - I have a seat cane and a pin keeps coming loose. The cane is 5 yrs old and other than that, works great, but I don’t want it falling apart and me ending up on the ground. It is aluminum so it can’t be welded. I put the Blue Magic liquid steel on the end and it works great. A new cane would have cost over $120 and the new ones are not as comfortable. I tried and sent it back, then tried Blue Magic and I’m SAFELY back in business.

## Questions & Answers

**Q: How to properly cure? The instruction is hard to follow.**
A: I don't remember how the instructions read.  But I let it set at room temperature for a day and then put on the second application.  I let that application set for several hours and then I put a small heater blowing on it for several more hours.  My fix was a hot water boiler exchanger and so it was an extremely demanding spot.

**Q: would it seal a crack inside a wood stove?**
A: I used it on an Ford f250 exhaust manifold I know the temp is hot in that application. Not sure on wood stove cast iron or steel ? I personally would give it a try. but if your using this stove inside a home you'll need to keep a close watch on results.

**Q: Can I use this to repair rust holes at the bottom of my oven?**
A: I would think so though I have not used it for that. Ovens rarely exceed 600 degrees F. I've used it on motorcycle exhaust manifolds that are near that range without issue. Be sure to clean rust first and sand lightly for good adhesion.

**Q: Will this give loose exhaust manifold studs in cylinder head extra strength? There is still thread left, looking for options before heli coil**
A: I used this on an exhaust manifold, it burned off on the first drive. I don't think that it will hold up.
