Mipa HV cavity sealant 500 ml aerosol includes a 60 cm spray probe for enclosed areas such as sills, doors and folded sections. The transparent brown wax based coating is made for corrosion protection inside vehicle cavities.
Hidden corrosion protection
Hidden cavities, sills, doors and box sections need a creeping wax film that reaches areas a brush cannot reach. This guide helps choose between aerosol cavity protection with a probe and sprayable 1 l cavity sealant for larger preservation work.

Mipa HV cavity sealant sprayable transparent 1 l suits larger preservation work where several cavities, box sections or repair zones need treatment in one session. The sprayable format is useful when a suitable cavity gun or applicator is available.
Use existing holes, drain openings or removed bungs where possible so the probe can reach the closed section without unnecessary drilling.
Remove loose dirt around openings and protect nearby trim, glass and painted edges from overspray or wax residue.
Feed the probe into the sill, door or box section before spraying so the wax begins at the far end of the cavity.
Apply the wax while slowly pulling the probe back. This helps distribute material along the length of the enclosed section.
A small amount of visible wax at seams or drain points confirms reach. Wipe exterior residue clean and keep drainage openings functional.
The aerosol with 60 cm probe is practical for sills, door bottoms, repairs and smaller preservation jobs where direct reach matters more than volume.
The sprayable 1 l format is better for repeated work across several cavities or restoration projects where more material and a dedicated applicator make sense.
Work methodically from one access point to the next and keep a simple note of which sections have been treated. Hidden cavity work is easiest to forget because the finished protection is mostly out of sight.
