Welcome back to the Bogus 2 build series, brought to you by Mini Sport Ltd.! Today, we're revisiting a crucial aspect of the restoration process – body repair.

While our previous blog posts delved into the details of the repairs, this one focuses on practical tips you can apply to your own classic Mini. We'll be drawing on insights gleaned from Bogus 2 and the expertise of our Mini restoration specialists.

Stonechip Protection: Don't Forget the Underside!

While Bogus 2 didn't receive stonechip protection for the entire underside, it's a valuable addition for many classic Minis. This protective coating shields vulnerable areas from the harsh elements they encounter on the road. At Mini Sport, we typically recommend stonechip paint for the sills, but a full underbody coating can be a great option for added peace of mind, especially for cars that see frequent use!

Sealing the Seams: Keeping Rust at Bay

Seams are a potential weak spot for rust development. As you can see with the Bogus 2 front wing and front panel, even seemingly small gaps can invite trouble. That's why proper seam sealing is essential. We recommend treating all seams, including the headlight ring, to create a barrier against moisture and corrosion.

Seam Sealer Application

Applying seam sealer requires a delicate touch. The goal is to inject a bead deep into the seam using a continuous, steady motion (ideally after the panels have been dried thoroughly). Use your finger to push the sealant in, leaving a visible seam line. Don't overfill, as this can lead to paint cracking later.

After applying the sealant, remove excess residue with thinners (remember, this example uses bare metal, but ideally, sealing happens after priming). The key here is timing. The sealant should be tacky when the final paint layers are applied, allowing for proper adhesion. Completely dry sealant will lead to paint cracking.

Joddling Panel Edges: An Alternative Joining Method

Joddling is an option for joining larger sheet panels. This technique creates a step in one edge, allowing the other panel to fit snugly in the seam. Joddler tools can also punch holes for plug welding, but keep in mind that these areas may require additional sealing and welding for a watertight finish. Mini Sport often favors other methods due to these additional steps.

Clamping Solutions for a Flawless Finish

Clamping the joined sheets is crucial to avoid distortion. Our example showcases handy Micro clamps, perfect for creating a flat and secure seam.

Remember, these are just a few key body repair tips, we always recommend contacting a reputable body repair expert! For a comprehensive restoration experience and access to top-quality parts, contact the experts at Mini Sport Ltd. We're here to help your classic Mini reach its full potential!
