General Products hull

The most famous (and most profitable) items produced by General Products are General Products hulls, which are advertised as being impervious to anything apart from visible light (as defined by wavelengths visible to any of the species which are customers of General Products), antimatter, and gravity. The hulls are advertised as being capable of passing through the upper atmosphere of a star without damage, although the contents may become overcooked (but see below for a solution to this problem). The company even offers a guarantee that, should anything harm you within a General Products hull as a result of a failure of these specifications, you (or your estate) will receive a very large sum of money ("tens of millions" of "stars" in the event of a death, with a "star" having value roughly equivalent to one United States dollar

, states that around 95% of all contemporary spacecraft are built around a General Products hull.
Nothing, but nothing, can get through a General Products hull. No kind of electromagnetic energy except visible light. No kind of matter, from the smallest subatomic particle to the fastest meteor. That's what the company's advertisements claim, and the guarantee backs them up. I've never doubted it, and I've never heard of a General Products hull being damaged by a weapon or by anything else.

 and exposure to the "blind spot". To provide further protection, the hulls are normally lined with 'flare shielding', which instantly becomes reflective to any of the transmitted visible light wavelengths should the intensity rise above a certain threshold.

Furthermore, since the Puppeteers are careful to an extreme degree to avoid any risk at all, they don't trust even these hulls completely. They have therefore installed in at least two (and possibly all) of their ships a 'Slaver Stasis field', which stops time inside the hull instantly should anything bad happen, and keeps it stopped until the bad thing goes away.

, the characters learn that the bonds of the giant molecule are "artificially strengthened" by a small power plant in the hull. By aiming a very powerful laser at it (since GP hulls are transparent to visible light), one can destroy the power plant, and destroy the hull. Gravity attracts the hull and its contents normally, but not even close approach to the event horizon
Event horizon
In general relativity, an event horizon is a boundary in spacetime beyond which events cannot affect an outside observer. In layman's terms it is defined as "the point of no return" i.e. the point at which the gravitational pull becomes so great as to make escape impossible. The most common case...
