Used this to keep the cut and soldered edges of a ws2812B LED strip on a child’s toy water resistant while it sits outside year round under a tarp. Works like a charm. 10/10 would recommend.

I bought this to protect some reflective tape on some 10mm fiberglass rods i was using for outdoor markers. It shrinks clear, but is very thick. Even though it advertises a 4:1 shrink ratio, i recommend choosing a size as close as you can to the object you are shrinking to.

I like the shrinking and was fairly happy with the clarity, though I do wish it was 100% clear. It is also strong resistance to cuts

It is solid, thick shrink tubing but seems the same as 3:1 shrink tubing and glue is very thin, negligible often.
