How Do I Remove Rust from a Boat Trailer?
When it comes to removing rust from a boat trailer, the key is to neutralize the existing rust before it spreads. Using the KBS Coatings Ultimate Frame Coater Kit, this process is straightforward:
1. Remove Loose Rust and Paint
- Use a wire brush, 320 grit sandpaper, or sandblasting.
- Lightly scuff any well-adhered original paint with 320-grit sandpaper before proceeding.
2. Clean the Trailer with KBS Klean
Thoroughly wash all areas of the trailer to be treated using KBS Klean. Clean surfaces allow KBS products to work most effectively.
- Mix KBS Klean with warm water and scrub with a sponge or bristle brush.
- Rinse and dry thoroughly.

3. Neutralize Rust with RustBlast
For areas with existing rust and bare metal, RustBlast is applied to etch the metal for best adhesion of RustSeal.
- Spray on and keep wet for 30 minutes–2 hours depending on the amount of rust.
- Scrub intermittently with a Scotch Brite pad.
- Rinse and dry thoroughly.
- A whitish residue will remain; this prevents flash rust. Do not remove.
