MG Chemicals419D-P Clear Overcoat Pen for Electronics - Protect and insulate circuit board traces, 5mL

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

It covers bare circuit board traces well and makes the job much neater. I like it.

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

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.

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.

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

Great product would buy again...https://mobilemedics.com

Bought this and went to use it when my last pen was used up (three months after purchasing it) and the pen was completely empty. It looks new, but had nothing in it. Disappointment...

Very good product, easy to apply and drying fast. Highly recommend it.

a utilisé sur de la grosse carte mère style ordinateur et autres car épais.

When you need it to cure fast without equipment to help this did the job and made our boards that had damage look more professional thanks
