will gasoline affect it

As far as I know the only thing that will affect this thread locker is high heat from a torch.

How long does this product need to dry for?.

The parts will be set in a minute or two but they recommend 24 hours for full adhesion. If it tends to set up too quickly for proper alignment of the parts you can slow down the process by putting them in the freezer for ten minutes or so. You have to dry them off and remove condensation or moisture but I will provide a longer set up period - perhaps two or three minutes. Thereafter it will not be possible to remove or adjust the parts. The total cure time will remain at 24 hours for full strength.

The bottle i just received of 272 (50 ml) doesn't say "high temperature." on it like i was expecting. should i be worried? i do need high temp.

LOCTITE 272 is one of our red, high- strength threadlockers. The temperature range of this product is for applications -65 to 450 °F.

is this kind removable when needed?

Its not really made for being undone. You can remove the bolt if you apply a lot of heat. There are other types of loctite that are made for removal of the bolt.
