Perfect!
Perfect match for old power supply with quite a few exposed traces! This little bit goes a looonnng way!

Fix those exposed traces
A little expensive but works as described. Remember to clean your PCB first to get off any flux residue, dirt and possible corrosion.

Pen was mostly empty
There was enough in the pen to cover the few small areas of the PCB that I had repaired, but just barely. Given that other reviewers have mentioned the same problem, I'd steer clear of this product. The actual coating works well, but the pen doesn't seem like a reliable way to buy it.

Application fell off
I was using on a CPU under the IHS to protect some components while do liquid metal cooling. I applied 3 layers, waiting a day in between each for it to dry fully. But the whole thing came off in the end, and I ended up instead using some clear silicone sealant, like clear caulking used around sinks, the same adhesive I used to reattach the IHS. So this ended up being a total waste of money since it's not refundable due to being flammable.

Adds a finishing touch to a job.
It covers bare circuit board traces well and makes the job much neater. I like it.

Must have.
Great for covering tiny scratches on PCB when de-paneling by hand.
