Restrict access to bootcamp partition

Is this possible?

No.

I thought I would be able to do this under get info for the drive, but in the sharing and permissions it just says "you have custom access", with no option to change anything.

FAT32 partitions don't use permissions, and Mac OS X can't change the permissions on an NTFS drive.

I'm no expert, but I have a theory, and do let me know if this helps. If anyone knows more, feel free to comment as you probably have more knowledge than me.

For one, I understand that bootcamp partition permissions are dependent upon the format for the partition.
-NTFS does not allow you to modify anything at all/
-FAT32 allows you to modify access permissions, including read and write.

First you should probably re-partition the drive into a FAT32 format so you can actually read and write.

Then, while on an Administrator account, Get Info on the Partition Drive.
Your list of accounts and permissions should be listed below.

You could probably then, when looking at the group "Everyone" you could change the partition to "No Access."

I've noticed you can also add specific accounts onto that list, but that does not allow you to specifically give that person "No Access."

So, I am thinking that you could maybe set "Everyone's" access to No Access, but add Administrators and/or other specific account with Read and Write.

Let me know if you think this could work. I do suggest asking others before doing it though just because I am no expert.

First you should probably re-partition the drive into a FAT32 format so you can actually read and write.

If it needs to be used to boot Windows Vista or 7, that's impossible. These OSes require NTFS on the boot drive. And even if it's done with Windows XP, FAT32 doesn't support file permissions, owners, or groups.
