Abstract: The invention relates to a method of cavity sealing a motor vehicle component, which comprises the following steps: a.) spraying of a cavity sealant into the motor vehicle component; b.) allowing the cavity sealant to penetrate; c.) allowing excess cavity sealant to drip out from the motor vehicle component; and d.) curing of the cavity sealant, whereby the cavity sealant comprises a crosslinkable component. Step a.) is thereby preceded by the step of mixing in a crosslinking component, whereby the amount and type of the crosslinkable component and of the crosslinking component are selected so that the cavity sealant solidifies to a gel-like consistency between step c.) and d.).
