If it's honeydew, then soap & water should do the trick. Do not use harsh soap. An alternative method is to use a gritty, oily mixture to rub it out. I'm thinking maybe baking soda & vegetable oil. The grit helps break up the sticky substance, and the oil keeps it from re-sticking. Similar to using peanut butter to get gum out of your hair. Then ...
From experience with small sections I have used hand sanitizer and it works. My parents used to use baking soda for our pop up camper. It was a thicker material then a tent, but it cleaned and absorbed a lot of sticky substances.
It is most likely not sap but the excretion from Aphids (Greenfly). They suck the sap from the tree and then excrete this sticky substance, often called Honeydew. It may be worth contacting the tent manufacturers for advice, but I would suggest careful washing first with just water and if that isn't enough, try with some soap flakes (like Dreft).
The main issue with repairing plastic hulls is that is that most adhesives don't bond very well to the plastic. For temporary repairs duct tape is the way to go. Its quite adhesive and waterproof. If the hole is too big use the duct tape to secure something else waterproof (e.g plyboard or plastic) in place. If possible try and do both inside and out. If ...
It's quite common to melt in some plastic - but be sure to get the same as the boat is made of. Most are PE so try to get some of that -- avoid ABS. Kits are available (random web example). The general recommendation among people I know who've done this is to use a hot air gun rather than a naked flame. You can also overfill a touch and smooth down ...
For from upto small leak holes to upto coin-sized holes, You can possibly use a Duct tape on the both sides. One more thing to add between the Duct Tape's point of contact is a filler like Some local Epoxy Compound product, or worst case a Chewing Gum (Chewed one :D). For a crack, you might just get it fixed by a Duct Tape.
I've seen people use a soldering iron and a piece kf abs plastic to repair tears in the hull but the best answer is short and simple to use for small holes: epoxy putty. just follow instructions on the packaging, fill the hole with a small (few mm) overlap inside and out and if you want sand down when hard and paint.
