MG Chemicals 419E Premium Acrylic Conformal Coating for Electronics - UL 746E Recognized, 12 oz Aerosol, 340 Grams

Use this to provide an additional layer of protection for the circuit boards going into devices that I used outdoors. Does what it is supposed to do.

Used to protect circuit boards in our campervan build

I finally got around to using this after several weeks. This was a disaster. First when I pushed the button to release the coating, it sprayed a black residue instead of clear. It then began to leak all over and finally just clogged up and would do no more. This was a waste of time and money.

When installing new control boards , I spray them all and seal them due to moisture and dummy cleaners who like to wash every thing with a hose

I've been using MG's conformal coatings regularly for about a year now, in this time I've used at least 10 cans. The quality of the product is great, however each time I come back to order another the price has increased by a few dollars, so much so that the price has doubled for some of these aerosol cans in the time I have been purchasing them.

This product adhesion is very poor, I applied to coat a printed circuit board, this coating is supposed to be good quality - NEVER purchase, I usually use Techspray coating, and the worst part this company knows there product is the worst and I cannot return it, Horrible Experience

Went to use this thinking it would be a good idea to protect some circuit boards but the can didn't spray out the nozzle it discharged out the stem and all over everything except the circuit board. Thought it was a fluke and tried to clean/readjust the spray stem but it did the same thing spraying out all around the stem, this material will definitely stain anything it touches. Very disappointed.

Aerosol nozzle arrived damaged. Managed to salvage enough product to complete the required work. Disappointed considering the price.

Don't know much about the product, first time trying to use the nozzle was plugged and the spray valve in the can got stuck and it sprayed out everywhere and got all over my hands, just about in my eye and made a huge mess and would not stop. Had to set the can outside and watch and listen to 33$ literally blow away in the wind. Totally unusable and a total waste of money. Not impressed.

Can emptied all at once. Manufacturer indicated a month ago they would send a replacement none has arrived. I have followed up and no response. Buyer beware.
