Cavity Coater

Yes, absolutely. You can spray the back sides of fuses and relays with Cavity Coater to prevent corrosion which commonly happen under the hood. That is an ideal application.

Please be sure to read thoroughly the Cavity Coater Directions and let us know if you have any questions.

You can reuse the Cavity Wand almost indefinitely.

After each use, simply flush residual Cavity Coater from the Cavity Wand by inverting the Cavity Coater Aerosol can and spraying for 10 seconds to flush Cavity Wand. If you do this, the Cavity Wand will be ready to use the next time it is needed.

Please be sure to read thoroughly the Cavity Coater Directions before you get started and let us know if you have any questions.
