Review: Works Great for Outdoor Repairs - This patching compound worked really well for sealing and repairing small cracks and gaps. It spreads smoothly, dries solid, and holds up nicely against weather and moisture. The white color blends well with most surfaces and can be painted over once dry. A reliable product that does exactly what it should — great for outdoor use!
Review: Perfect for our application - We used this to patch an outdoor statue that was damaged by a storm. It filled the hole and bonded on the first attempt. Also held the paint. Worked better than advertised.

## Questions & Answers

**Q: Does anyone know how to prevent the unused portion in the plastic can from drying up before I have a chance to use it?**
A: Scrape all material off the container wall, then put a piece of Saran Wrap over the rest of the unused portion. Not on the top of the can, push it right on the material inside the container then put the cover back on. Works great!

**Q: Will it work to patch a chip/gouge on PVC trim?**
A: I haven't done that personally, but I think that's exactly what this product for. It is essentially sandable filler for PVC (and other materials).

**Q: Is it stainable?**
A: Hello,
Yes; To test, I applied some of the platinum patch to a small canvas, allowed it to dry, (did not sand) then applied some black Gel Stain to the canvas, and it took really well. 
Good luck with your project!

**Q: Would this work to fill a crack on composite decking?**
A: I would bet so. I have  used it on everything else like wood, steel, hardy board, plastic, and concrete. It does come in a 16oz. Plastic bucket and its sandable too. If anything is going to work on composite decking its this product. Love this stuff !

### ⭐⭐⭐⭐⭐ This stuff is the finest wood filler putty for outdoor applications
*by J***S on November 14, 2024*

This product is very uniform and easy to spread, you can level with easily, it dries extremely quickly. Once it's dry, it's easy to sand flush. You can fill large holes you can fill salt small holes. You can fill flat shallow holes. Once it's dry and over painted, it's essentially weatherproof. I don't know why anybody would use anything else unless you want a complete curing system like Bondo. This is not structural it's just for cosmetic, but you can rebuild massive areas of loss very easily. It's hard for you to believe how fast it drives.
