The side trims with a black stripe down the middle fitted to late Cheltenhams are from Hillman Super Imp motor cars. These are becoming rare in scrap yards, so fellow owners might consider it wise to obtain some spare lengths if they see it, also keep your eye out at auto jumbles.
Maintenance
Interior Wood
Lifting Veneers - If the oak veneer starts to lift and you don't want to replace the whole panel it is worth trying to spray gently between the 2 panels with “Bostik Fast Tak” spray adhesive, letting dry for a few minutes and pressing together with a wallpaper seam roller.This adhesive is available from branches of Wilko.
White patches - If you have white patches on the wood in a Cheltenham with medium oak veneer (usually where the wood has got wet & then dried out) try Pledge Extra Care scratch & colour restorer Light/ Medium wood, this brings the colour back to the wood. This is available from branches of Wilko.
Dry Wood - The interior wood in a Cheltenham dries with age, life can be bought back to the wood with Danish oil, this is readily available, try Wilko or Toolstation.
Worktops - Stains & marks can be removed from the Formica worktops in the kitchen area using Autosol metal polish (the same is recommend for aluminium window frames), readily available from a range of stores including wilko and motor stores .
