I got a new guide tarp from Chinook last year. Same size and composition as the previous one, but with a silverized interior, which noticeably reflects a lot of heat and light into the shelter area from the fire out front.
I was wondering if some newfangled Dyneema/Cuben fiber would be more pinhole spark resistant. I’ll never know; those tarps are well out of my price range for that sparky fireside use. But you have provided the “Duh, I already own one” candidate answer.
I use a back-porch awning tarp at the tailgate end of the truck. After sweating out one over-temp desert trip I realized that a silver reflective tarp would be beneficial for reflecting the heat of the sun when parked for the day.

Even with a white cap it was oven-hot inside, and the only shade was beneath the canoe overhang. That didn’t do the ice in the cooler any favors, I could make tea with the potable water without needing a stove, and the baked into the gear heat under the cap took a long time to dissipate after sundown, which is my usual bedtime. Improvements were needed.
I found a 9x9 poly tarp, silver reflective on one side; an inexpensive 2lb 2oz Yuedge, surprisingly well made and did some experiments with it under blazing summer sun.
The truck bed under the cap stayed noticeably cooler and, checked in non-desert use with a thermometer and hygrometer, surprisingly less humid. I surmise that there is often dampish gear stored in the back that pumps out moisture as it further dries in the heat.
The sun reflective results were excellent in any environment, except the 9x9 Yuedge wasn’t wide enough to provide cover over the cap’s screened side windows, especially with a canoe on the roof racks. I needed something larger, so I could open cap windows in the rain, and bought another reflective Yuedge, a 10x13 this time.
That size was perfect; extending out over the cap windows.

And still providing a decent back porch over the tailgate end.

With a canoe (or two) on the roof racks it doesn’t even need poles, the racked canoe keeps it lofted carport high over the windows and tailgate, so set up is as easy as staking down attached side guys. I use a tennis ball with attached cord to throw the far side guy lines over the cap and pull across evenly; easy peezy stake out quick set up. And, when moving on pre-dawn the next morning, fast dark-of-night take down. Pull the stakes, shove everything in a ditty bag, hit the road.

Not only a cover for the side windows in the rain, but also a portico between the cap/tailgate end and cab doors. There always seemed to be some piece of gear stored in the cab that I wanted in the rain; “Dang it, the umbrella is up front”. That covered walkway between the cap and cab doors proved advantageous.
That was, as usual, a very long way of saying that I have a 9x9 silver reflective poly tarp that has seen no use in several years. At $30 it will do nicely as a fire’s edge tarp extension, patching pinholes be damned.
quote="guyfawkes041"] After a trip, I lay out a strip of Tenacious Tape onto a piece of wood, and using a 3/8" dia hole punch and mallet, bang out enough patches for the tarp each time. Ten years is not exactly a throw away approach, and there is still much life in the tarp. [/quote]
And this is why I love gear and technique discussions. I am a big fan of Tenacious Tape, but right-angle tape patch corners are a no-no. I have grommet kit punches in various sizes. It never occurred to me to punch out circular patches. Thanks for that suggestion.
And thanks for the heat-reflective suggestion; sometimes I can’t see the forest for the trees. I buried that little Yuedge on the tent & tarp shelf, and never really gave it further thought beyond “Wish I’d bought the bigger one to start with”
I’ll bring the 9x9 Yuedge next time I use the Tundra Tarp and see if/where I need to add quick attachments to pair with the Tundra Tarp webbing loops, for use as a fire’s edge or side wind block auxiliary tarp.
I don’t see either Yuedge version currently available, but there are plenty of small silver reflective tarps priced cheaply enough to be years of patched pinhole semi-sacrificial.
