Paint motorcycle engine covers

Motorcycle engine cover high heat painting

Guide to painting motorcycle engine covers

Motorcycle engine covers need a clean and keyed metal surface before a heat resistant coating is applied. The finish must be kept away from sealing faces, fastener seats and internal surfaces while visible exterior faces receive the Mipatherm coating.

What do you need to paint motorcycle engine covers?

Cleaning and degreasing

Mipa silicone remover removes oil, grease and handling marks from the exterior coating area before sanding.

Sanding and surface keying

The MP Sanding Pad prepares stable metal or old coating so the high heat finish has a keyed surface.

Liquid heat resistant coating

Mipatherm gives a black or silver high heat coating for suitable steel surfaces exposed to high temperature.

Aerosol heat resistant coating

Mipatherm Spray 400ml gives a practical aerosol method for smaller engine covers and visible hot brackets.

Masking of functional faces

Mask sealing edges, bolt seats, gasket faces, machined contact areas and inside surfaces before applying coating.

How to paint motorcycle engine covers

  1. 1
    Remove oil and dirt

    Clean the exterior coating area thoroughly with silicone remover before sanding.

  2. 2
    Sand paintable faces

    Key the visible exterior surfaces while keeping machined, sealing and threaded areas protected.

  3. 3
    Clean again

    Remove sanding dust and residue so the high heat coating is applied to a clean surface.

  4. 4
    Apply Mipatherm

    Apply Mipatherm or Mipatherm Spray in controlled coats according to the chosen application method.

  5. 5
    Cure before heat exposure

    Allow the coating to dry and follow Mipa curing guidance before exposing the part to engine heat.

Which Mipatherm format should you choose?

Aerosol engine cover work

Use Mipatherm Spray for smaller visible covers, brackets and local heat exposed exterior areas.

Liquid spray work

Use liquid Mipatherm when the job suits spray gun application or multiple parts are being coated together.

Functional area protection

Mask sealing and contact faces because coating build can affect fit, sealing and fastener seating.

Technical details

  • Mipatherm is a matt high heat resistant special coating based on silicone resin for steel substrates such as exhaust systems, ovens and barbecue grills.
  • Mipatherm and Mipatherm Spray are heat resistant up to 800 °C according to the Mipa technical information.
  • Mipatherm Spray technical information calls for pre-cleaning with Mipa silicone remover.
  • Do not coat gasket faces, internal oil contact areas, machined seats, threads or mating surfaces.
Practical suggestion

Photograph the cover before removal and mark every gasket edge, bolt seat and contact face that must stay uncoated. A clean paint finish is not useful if coating build prevents the part from sealing or fitting correctly.
