Re: Advice Regarding Best Adhesives

White glue is water soluble, even after it dries, while Elmer's Carpenter's
glue is recommended for exterior applications and doesn't dissolve once set.
I was under the impression that yellow glue like Elmer's Carpenter's Glue
and Titebond were aliphatic resins, so they wouldn't be the same as white

Elmer's glue is "white glue" ... even if you are using the yellow
version aka "carpenter's glue". Elmer's does not always dry "clear"
(especially the yellow one). There are several different brands of
white glue - all of them are based upon using the natural adhesive(s)
in milk.

MicroScale sells a product called Krystal Klear. It comes in a
small white bottle with blue lettering and you will find it at your
local hobby shop. KK is essentially a white glue that has been
thinned with something and re-packaged into small bottles to be
sold to the hobby. MicroScale sells it to be used for windows
(hence the name Krystal Klear) ... but it actually works better
as an adhesive than for windows (tends to look like the proverbial
"coke bottle glasses").
I use KK a lot more than any other form of white glue. Because
it is already on my work bench. I apply KK by dipping a round
toothpick into the bottle and then using only as much as I need
and where I need it.
The thing I love about KK is that it doesn't 'wick' ... it 'flows'
(at most). And when it dries it forms a "fillet". I first started
using it when I was attaching the sunshades to painted diesels but
since have taken to using it for lots of other things. Among those
uses is that it is my adhesive of choice for adding weight.
KK does not soften due to humidity - but if you put a drop of
water or two on it and let it set it will soften and you can remove
and redo whatever it was holding.
I rarely use KK for "windows" ... but I often use it to form a
headlight/other light lens. And also to 'encase' LEDs in the same
light fixtures or to attach an LED to the back of an MV lens.
One of the advantages of using it for attaching LEDs is that it
also becomes the insulation so the wiring can't short out.
