WEICONIsolation Spray – Clear Insulating & Protective Coating for Electronics | Waterproof, UV-Resistant Varnish for Circuit Boards, Motors, Wires & Electronic | 13.5 fl oz

> took awhile to procure but seems to have abated my compromised copper trace problem to date…

expensive, but not any better than any other acrylic spray. I thought there was some sort of magic, that the acrylic paint creeps along the surface and covers all areas which otherwise would be free of this coating... no it does not. Waste of money.

Review of ”WEICON Isolation Spray | 400 ml | insulating and protective varnish for sealing & ...":(Please refer to my reviewing guidelines at the bottom of the page).We live on our 52' Trawler 100% of the time and anchor out and travel 99.99% of the time. There are many electrical connections and circuit boards on a live-aboard boat and many of the connections are exposed and in the outdoor wet environment, or even indoors in the bilge area. We use both dielectric paste and dielectric spray (like this) for sealing electrical connections against corrosion and it works very well. We also use the spray for sealing electronic circuit boards that are not in a waterproof enclosure.This spray has a clear appearance almost like a clear polyurethane paint. It's very easy to apply to connections or circuit boards. They don't suggest this on the can but I recommend you let the first coat dry until barely tacky then give a second coat while making sure you get in and around all of the areas that you want protected.This spray is nice for cases that may need rework in that you can still do circuit board repairs or modifications without removing the cured spray in advance. In fact, I've also been able to do good solder joints on a board that had already been sprayed but not yet cured.I'm giving this 4 stars because it is a good quality dielectric spray in a decent size 13.5oz can for the price.My responsibility as an Amazon Vine Reviewer:Considering the Amazon rules/regulations for being a Vine Member It is obvious that it is very important to Amazon that the person doing the review has indeed inspected, tested, used the product as well as being aware of the competitive situation of the market segment. This is so it can be fairly compared and reviewed whether good, bad, average, or anywhere in all of the grey area between. One thing that I wish were better defined by Amazon is exactly what each star should represent from 1 to 5 so that every Vine member would use the same guide in that regard. So, to let you know the guide that I use, I include it as follows:I always start off considering that average is 3 stars, and an average rating to me is:The product was correctly represented in the ad.The manufacturing quality is as expected.The product performed as intended.The product operating/user guide if needed is helpful.The product is priced accordingly.Then after inspection, measuring, testing, using, wearing, or whatever is requiredI add or subtract from the average as follows:Subject to additional stars:Additional product features not expected that are useful.Manufacturing quality/performance above what was stated or expected.Included guides and/or useful information that is beyond the norm.Product pricing highly competitive for a superior product.Subject to fewer stars:The product was misrepresented in the ad.Manufacturing quality/performance below what was stated or expected.No useful guide or understandable user information when required.Product pricing is on the high side considering quality, features, or the market.all the best,dr

Used to coat printed circuit board to prevent corrosion in humid environment. Coated board and dried quick leaving clear silicone like seal. Will update after 3-6 months of use.

This is some good clear insulation coating, it does a good job, nice coverage and dries quick, I like that is clear so I can still see the condition of the work, very good stuff.
