It's persistent - the flame treatment makes it a lot less smooth to touch.
I am sure there is a scientific explanation :)

 Do you dare post it on Figjam's ePlaya thread about swamp coolers
 , or do you think
 that's just asking for unkind comments

Interesting! Does it still have to be hot when you apply the adhesive, or
does heating it once make it persistently friendly?

 [image: IMG_20180724_195151114.jpg][image: IMG_20180724_195216011.jpg]

 The vessel is a swing-lid trash can
 ,
 and the filter holders are cheap-ass soffit vents (two wide
 
  and one narrow
 )
  from
 the ventilation-and-flashing aisle, both from HD. The evaporative area is
 more than 50% larger than my old bucket cooler, the water capacity two or
 three times greater, and since the fan points horizontally (i.e, toward the
 yurt rather than the sky), it requires a fraction of the length of duct to
 get to the building, so I expect higher flow AND less heat gain. I haven't
 been out to the Playa with it, but I'm getting 5°F cooling at 68°
 temperature and 68% humidity.

 The pump is a 3.6W 12V aquarium pump (2 for $15 at Amazon
 ), and that white thing at the bottom is a float
 switch  to cut it off when the water gets too
 low.

 It has a cigarette-lighter male plug for power in, so I can either run
 it off a car battery or 12V solar panels. At the top, barely visible on the
 right, are simple 12V voltage regulators for the fan and the pump. I bought
 a pair of these solar panels  years ago, and
 those voltage regulators are all the control you need (I think they were
 $1.69 at my local electronics depot, ad I have two, one for the pump and
 one for the fan, just b/c they're so wimpy).

 The lid was a bit of a mission to build, because you want a good seal,
 yet the bin has rounded corners.
 You'll have to follow this link to see what I mean.
 
 Rather than try to duplicate the bowing of the box, I exploited it by
 gently forcing it straight, to provide pressure against the outside. (I
 used the dado blade on my table saw to cut the channels, but you don't
 really need it to be held on both sides.) For the curves, I used Bondo:
 plopped it down inside the lid, greased up the bin with butter, put it in
 place and let it define its own shape. I suppose you could work from the
 inside and pile more Bondo up on the lip, but that felt like overkill to
 me. You could also do it entirely with Bondo, allowing the box to keep its
 natural shape, only if your Bondo skills are better than mine.

 So will a hot, dry Playa give me enough temp. drop to sleep in? We
 shall see. It does seem to be moving a lot of air.

 Cheers,
 Steve Upstill

To get glue to work on these kinds of plastics we do flame/heat treatment
first - use a propane torch or a heat gun on high to soften the surface -
after that epoxy works just fine ;) Let us know if it helps bondo or
silicone adhesion as well!

Thanks Jay! I'll probably keep this in the "family" until I've tried it out *in
