I'm not sure the chakra can help you avoid the adhesion. I've never seen it used like that so far and if it was, then the syrup techniques would be useless because everyone would repel them by simple chakra. You need a stronger technique to repel the effects and to get rid of the adhesive.
Advantages:
There are many advantages to this technique. for example the oil is a very highly flamable substance. So, the answer is obvious more than direct combat this can be used as a combo beast. For example the technique oil flame bullet used by Jiraiya. Since oil is highly flamable it used in combo with the fire jutsu to drastically increase the damage caused by the oil techniques. The oil spreads out to a large area. So if a fire tech is used with a oil tech there is more propability that the fire jutsu will affect the opponent. Next is the Syrup. thought the syrup's are highly viscous in nature and doesn't flow fast, they can be used as a excellent medium to trap the enemy because of it's adhesive property. like how kakuzu was trapped by stick syrup. As soon as the enemy is trapped it will be difficult for the opponent to come out of the trap thereby giving us some time to perform powerful precision based jutsu on the opponent that requires the opponent to be paralysed or stationary in one place.
Disadvantages: There are many disadvantages to this method too. for example. the flow of oil/syrup is not as fast as water so if the opponent is aware of it he can easily dodge it. These can't be used directly in combat. using in conjugation with som other element only will improve the efficiency of the method. Oil can be considered as a double edge sword. since oil is highly flamable and mostly oil based techs will be stream type, when producing the oil for combat the opponent can take advantage of it and can use it against the user by using a fire tech against him. generally the combo's will need a clone to perform the other jutsu as if the user performs the jutsu concurrently , there will be a time lag between the jutsus and the opponent can take advantage of this. Regarding the syrup, If the opponent is aware that the user uses a syrup the opponent can nullify the adhesive properties of the syrup by focusing chakra in the part that will come in contact with the syrup.(eg. by focusing chakra in leg one can walk over the adhesive syrup.
The last method is called "Other". Basically, everything that isn't possible to be sorted in any of the previous groups falls in here. There's not really much to the method because the techniques vary and so do the advantages and disadvantages.
Now, we can start with the techniques. We'll do it this way. I will post the technique and I will in short explain how to perform it, strong points of the technique, possible uses and anything I find relevant and what I want from you is to give me your opinion on which method it belongs to and why. Then I'd like you to tell me how you could defend against the technique if it was used against you. You are free to use your imagination. This will give me a close insight on your understanding of the technique because if you're able to correctly defend against the technique, it means that you also know how it works. Understood?
