Caveat: I have this spray probe .....

... Not bought for the Liqui Moly Hohlraumversiegelung but to bring with you and with the help of an adapted spray the Hohlraumversiegelung Fluid Film Liquid A in cavities. Fluid film is based on lanolin (sheep wool grease) and penetrating oil and has approximately the viscosity of olive oil.

The probe has a total of 6 holes, once 4 and once 2 opposite. The probe is a total of about 61 cm long.
The spraying fluid film but only works satisfactorily - but better than all other probes tried by me. The vacuum sealing was not really atomized but rather entered into legally binding jets from holes. However, if you turn the probe on spraying by 45 ° back and forth can be still quite a good coverage of the plates reach the cavity.

I would reiterate the point: I have not used this probe with the vacuum sealing, for which she was well-prepared. Furthermore, I have only used a spray bottle.

I can say nothing about the proper application of Liqui Moly cavity protection.
