Rubber

Quest: Goes great with pancakes! ''Rubber can be gotten in 2 ways. MFR (MineFactory Reloaded) Rubber Trees, when chopped down, drop raw rubber, which is smelted into rubber bars.''

''The other way you can get it is by finding an IC2 (IndustrialCraft 2) rubber tree. These trees have 3 leaves on top. Don't chop the tree, but do remove all leaves but the ones directly above the logs. Some of the logs probably will have little blobs of orange on one side. Right click that side of the block with a treetap to get sticky resin. You can keep tapping it to get more sticky resin, but there is a chance that you will ruin that log, rendering it unable to grow more sticky resin. You can either smelt the resin to get 1 rubber, or put it into an extractor to get 3.'' Both types of rubber tree can be found in most forest biomes. The MFR rubber trees can be farmed like normal trees, raw rubber will drop when you chop it down and the logs can be smelted into charcoal. It also drops more than enough saplings to be sustainable.

The IC2 rubber trees, on the other hand, drop fewer saplings and should be left as grown trees. As stated in the quest book, you'll want to remove most the leaves because resin nodes can spawn on the upper blocks of the tree.

Craft a treetap and right click the orange node, just once. You should still be able to see a black outline where the resin was. This means the node can regrow resin over time. If the log turns into a normal log, you have over-tapped that node and it will not grow back.
