Don't be a Non-Conformist: Get Professional Results with no Ultra-Violet Curing.
Wear safety goggles. Very strong order, so use in a fan vented area. I coated both sides of an 8x4 inch (200x100 mm) PCB (for a washing machine) in a small bathroom with a vent fan on and it didn't stink up the house. Make sure the PCB is TOTALLY clean else the coating will pull back and leave uncovered spots. I use 95+ Isopropyl Alcohol with an Acid Brush (bristles cut to a stiff 1/4 inch or 6 mm) for cleaning and let it air dry. Make sure the board is above 60 F (16 C) and in less than 50% humidity for at least a day... you don't want to trap moisture in the board. It works well with an Acid Brush with 3/4 inch (18 mm) bristles. I applied the coating in one very thick coat, but two thinner coats may be better. The coating self levels and fully dried in 30 minutes (one side at a time). It is crystal clear and durable. Time will tell if it keeps corrosion at bay in a humid area like a wash room.

Perfect for HV supply repairs
Used it for re-applying insulating conformal coating on an HV 3kV power supply after a reapair. Worked perfectly, no more arcing. Use a mask and gloves when applying.

Dries fast, quality solution for circuit board sealant.
Dries FAST. Has a slight color hue in the glass bottle, reminds of high quality Aerospace coating. Used it on a circuit board in a salt air environment. Time will tell.

Works Great: Use Caution While Applying
I use this coating on PCBs that are milled on a CNC. Sealing these PCBs makes sense as I live in a high humidity environment. This material dries to the touch in about 30 minutes, but I give it 24 hours to fully cure. VERY IMPORTANT: 1) Heed the WARNINGS re the very flammable vapors and DO NOT breathe this stuff as it's quite dangerous. But, after it cures, the VOCs decrease enough that I can barely smell any. 2) Wear a respirator (Do NOT use a N95/KN95/surgical type mask), even if using outdoors. Also, wear safety glasses, and gloves (I use Nitrile) when applying. CLEANING: As noted, there are 2 included brushes. However, I use "acid brushes" (you can buy these in bulk) and both 70% and 99% isopropyl alcohol to clean the acid brushes. You'll need to use a paper towel and work the brush end to get the coating to "glob" up and detach from the brush. It's a bit of work, but you can reuse a brush several times. Handy Hint: Acid brushes tend to have 3/4" bristles. I cut these down to a tighter 1/4" for more accurate application. Have fun, but be safe! Picture: This closeup shows what a coated and non-coated area looks like after curing. When wet it has a slight pinkish tinge but, as shown, it dries clear.

Worked well but order more brushes
This worked very well to weatherproof some soil moisture sensors. Two brushes were supplied but you will need more. The brush hardens completely after a single use and the bottle contains enough for many many applications.

It's A Slightly Thick Acrylic Liquid - Does What It Says It's Supposed To Do
Dries very quickly. Acetone will thin it and can be used for cleaning it off of surfaces. Alcohol (IPA) does not seem to immediately effect it. Used it for applying a thin sealing coat to a magnetic sheet that has been sanded down to be very flat, thus I had removed the applied protective outer coating that this was used to restore. In general anything from MG chemicals is high quality. Use in well ventilated space and wear a respirator when using it.

Applies very nicely
Used the acrylic conformal coating to protect several circuit board in a 2000 Chevy Blazer automatic A/C control module. These control modules are very susceptable to printed circuit board (PCB) corrosion. The coat applies nicely and self levels. Hopefully, the risk of module failure due to PCB corrosion has been greatly reduced.

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.

Great product, UV illumination, brushes can be easily cleaned with Isopropyl alcohol and be reused, you should know that the acrylic does not bond to the surface, it is merely a coat that can be pretty easily scratched off, useful for rework but the board should be protected from physical damage or it will easily break seal. To protect from damage during manipulation, I would recommend the silicone modified coating or liquid electrical tape.
