What is the shelf-life of something like this? Will it stay usable if I buy this and don't use it until I need it for a long while off?
I just bought this and it didn't come with a brush cap. Just two brushes sperate in the pack? Anyone get the brush cap lately?
Does it effect led output when coated over led lens? I want to use on an led grow light to waterproof but I don't want to reduce the light output.
How is this different from 422B?

"Does what it says on the tin"

This conformal coating performs exactly as described..It's a reasonably thick, varnish like fluid that is easily applied using the supplied brushes (2 of them in the pack).The brushes are thin enough to fit into those awkward places, with the bristles being just the right size to hold enough, but not too much fluid. They were easily cleaned after use with White Spirit, so can be reused.The fluid forms an even coat that dries quickly yet performs well in protecting electronic circuit boards.At 55ml the bottle may look small, but it goes a long way. I coated both side of my cars control unit/fuse box without making a noticeable drop in the level in the bottle.

Took a while to dry

But I'm sold. It's very good and so far, it's holding up.Plenty enough to last.

Very useful for protecting

Protects very well the circuit board, must be very careful with products that contain rubber/etc.

Good for protecting your PCBs

Excellent product, easy to apply with a suitable small brush (you have to provide your own☹️)It helps if you have acetone or MEK to clean your brush out afterwards, too - not the easiest of solvents to use, but the most effective.

Posh nail varnish for electronics.

And at least you know the ingredients won't damage your PCB. Bought this for protecting circuits when delidding a CPU and applying liquid metal thermal compound. Also used for water protecting circuits of cheap LED floodlights.

Very good tuff, glad I made the purchase.

Have used this on my drone build, and to protect my brushless motor windings. what can I say.... its really good stuff, and it glows under UV light if your extra critical about making sure you get a good covering.

Spot on

Used to seal a PCB exposed to humidity, easy to apply and flows well!Goes off very fast so expect to buy more if you don't use it regularly and need it in future.

My drone is now a submarine

This is a staple piece on my freestyle build, it’s held up. I had a drone stuck in a quarry in rainy England. When I got the drone back and plugged it in the electronics turned on. Thanks to this
