Re: Cracked Basswood Colin,
Super glue comes in different thicknesses, where the the thickness dictates the drying time. There is also an accellerant they sell which thins and speeds drying. I have not used this for carving just for radio control planes.
Your best bet would be a hobby store that sells RC cars and Planes they should have a brand called Super Jet and sell the accellerant as well.
As far as discoloration goes, it turns the wood the color of wood treated with Boiled Linseed Oil, but sometimes if put on to thick will leave a white crusty film. Hope this helps.
