A damaged patch
Local coating repair

How much treatment does it need?
Several exposed areas
Wider underbody coating
For suitable floorpan, chassis and wheel-arch surfaces needing broader protection. Coverage and access are planned together.
Protection across agreed areasEnclosed metal sections
Cavity rustproofing
For applicable internal sections such as sills and accessible chassis cavities. Product availability and access are checked for your car.
Internal treatment quoted separatelySigns the protection needs attention
Peeling or lifting edges
Loose underseal needs preparation before a new layer can bond to the surface.
Exposed metal patches
Scrapes and stone chips can leave gaps in otherwise sound protection.
Rust around seams
Staining, bubbling or flaking near a joint deserves a closer look at the metal.
Damage after contact
An underside impact can damage the coating, a shield or both. Check the area before recoating.
Rust treatment or metal repair?
The metal and existing coating need inspection before treatment. A fresh dark finish cannot show whether corrosion was removed or whether weakened metal was repaired.
Sound existing protection
The original finish is firmly attached and the metal beneath is suitable.
Keep compatible protection in place and focus on any damaged edges.
Surface corrosion
Local rust or loose coating needs preparation before the new finish.
Assess the depth, prepare the area and use the appropriate treatment system.
Deep corrosion or holes
Flaking, perforated or weakened metal changes the job.
Assess repair or replacement first. A coating cannot restore lost metal strength.
Rust converters are preparation products, not a replacement for welding or sound metal. Flood damage and fluid leaks also need their own repair assessment.
Where the protection goes
“Full undercoating” means agreed coverage of suitable areas. It does not mean spraying every part beneath the car.
Floorpan and chassis surfaces
Suitable exposed metal and damaged protective finishes beneath the vehicle.
Wheel arches and sill edges
The agreed metal areas, including access behind liners where included.
Enclosed sections
Separate cavity treatment where suitable access and the vehicle construction allow it.
Working parts stay clear
Brakes, exhaust components, moving parts, sensors and drainage openings need protection from unsuitable coating. Covers and service points remain accessible for future maintenance.
Materials with different jobs
Rubber-based coating
Suitable exterior underbody and wheel-arch surfaces needing flexible stone-chip protection.
Texture, paintability and drying time depend on the exact product, not simply the word rubberised. Some undercoatings accept refinishing paint and others do not. Match the coating to the prepared surface and any finish being retained; a thick new layer cannot make loose coating or weakened metal sound.
Bitumen underseal
Appropriate non-visible underside areas, depending on the coating system.
Often leaves a dark film. Check compatibility and whether later overpainting is allowed.
Cavity wax
Suitable enclosed panels and structural sections reached through the correct access points.
Some products remain soft and non-hardening. They serve a different purpose from exterior underseal.
Prefer a particular 3M or other branded product? Mention it when requesting your quote so suitability and availability can be confirmed.
Washing, coating or cavity protection?
Underbody washing
Removes dirt and road deposits. It is part of care and preparation, but leaves no replacement protective coating.
Exterior undercoating
Adds a compatible finish to prepared underside surfaces. Cleaning, drying and repair needs come first.
Internal rustproofing
Protects applicable enclosed sections with a product intended to reach them. Exterior spraying does not automatically treat the inside of a sill.
Coastal roads, gravel and daily driving
The condition of your car matters more than its location alone. An intact factory finish may need only a check or a local repair.
Coastal exposure
Salt and moisture make damaged protection worth checking. Keeping the underside clean and attending to exposed areas are useful parts of corrosion care.
Gravel and off-road use
Check wheel arches and low underside areas after abrasive use or ground contact. A coating helps protect its intended surfaces; damaged undertrays still need their own repair.
Wet deposits behind liners
Road dirt can collect around covers and seams. Cleaning and drying those areas come before coating, especially where the existing finish is lifting.
From preparation to protection
Cleaning, surface preparation and drying give the coating a suitable base. Spraying is only one stage of the job.
Inspect
Check the existing finish, corrosion, contamination and any repairs needed.
Clean
Remove dirt and grease from the treatment areas and address active leaks.
Dry
Allow surfaces, seams and accessible recesses to meet the product’s requirements.
Prepare
Remove loose material and use compatible rust treatment or primer where required.
Protect and apply
Mask excluded components and apply the selected system to the agreed areas.
Check and hand over
Check coverage and refitted covers, then explain drying and washing instructions.
If cleaning reveals a larger repair, we explain the additional work and cost before proceeding.
Protection after body repairs
New paint on the outside is only part of finishing a repaired section.
Welding, panel replacement and seam repairs can disturb the original corrosion protection. Finishing the repair means considering the joint, exposed surface and accessible inner section.
When repairing a damaged floor or sill, we can discuss which protective stages belong with the repair and which additional undercoating would be useful.
Prepared metal and primer
The repair system determines the required surface preparation and compatible primer.
Sealed joints
Appropriate seam sealer protects the joint; it serves a different purpose from underbody coating.
Exterior and internal protection
Underbody coating and cavity treatment restore their respective areas where required.
Bring the previous repair invoice if available. It helps identify finishing already included and avoids paying twice for overlapping work.
Buying or protecting a used import?
Look beyond the fresh finish
Its previous use matters
Road-salt exposure, old repairs and earlier coatings can change the preparation needed. A recently blackened underside still needs its metal condition checked.
An inspection before buying helps you separate routine protection from repair costs. Bring any available repair or treatment records; you do not need them to start an enquiry.
New cars and EVs
Keep sound factory protection where appropriate. Manufacturer guidance and warranty conditions apply, especially around battery housings, cables and cooling equipment.
Driving, washing and future care
At the workshop
Allow time for preparation
Access, cleaning, surface work and application all count towards the visit. Repairs and extensive stripping can add time.
Before collection
Let the coating dry
Touch-dry, ready to drive and ready to wash are different stages. Collection follows the actual product and work completed.
After treatment
Care for the finish
Follow washing and chemical-use instructions. Keep drains clear and check damage after underside contact.
Touch up or recoat?
A damaged patch may need local renewal while surrounding protection stays in place. The product and its condition determine further treatment, rather than an automatic yearly replacement.
A few practical questions
How long does undercoating last?
The product, preparation, exposure and damage all affect service life. Use the treatment’s inspection advice and the condition of the finish to plan renewal. Any warranty has its own coverage and maintenance conditions; it is separate from a general lifespan estimate.
Can the old undercoating stay on?
Yes, if it is sound and compatible with the new treatment. Loose, contaminated or lifting areas need preparation. The inspection determines how much can stay, rather than automatically stripping the whole underside.
Will undercoating reduce road noise?
Some products have sound-damping properties, but results vary. The main purpose here is surface protection. A new rumble, vibration or mechanical noise needs its own assessment.
Is undercoating the same as ceramic coating or PPF?
No. Undercoating protects suitable underside surfaces. Ceramic coating and paint protection film concern exterior paintwork; cavity rustproofing reaches applicable enclosed sections. One treatment does not cover the areas served by the others.
Can a car with rust still be treated?
Surface rust may be suitable for preparation and protection. Deep corrosion, holes or weakened mounting areas need a repair decision first. We assess the condition before recommending the treatment.
