The liquid ultra must be a pain in the bum to apply and must be also extremely frustrating in fear you will short something out! I'm so scared of it to even consider it
Its piss easy to spread. There are youtube clips suggesting using a cotton bud and a great way to do it actually. However I found it far better to use a credit card. you get a perfect even covering. Not to mention the layer you spread is supposed to be thin. People often think its not enough and use too much.
