Does anyone know how to prevent the unused portion in the plastic can from drying up before I have a chance to use it?

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!

Will it work to patch a chip/gouge on PVC trim?

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).

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!

Would this work to fill a crack on composite decking?

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 !
