Paint engine covers and mechanical housings

Heat resistant engine coating

Guide to painting engine covers and mechanical housings

Engine covers and mechanical housings need preparation that respects heat, contamination and shaped cast surfaces. This guide uses Mipatherm, silicone remover and sanding tools for clean, heat-resistant coating work on suitable covers and housings.

What do you need to paint engine covers and mechanical housings?

Degreasing cleaner

Mipa silicone remover in liquid or aerosol format removes grease, wax and silicone before the surface is keyed for heat-resistant coating.

Sanding sponge

MP Sanding Sponge helps key curved covers, cast housings and small mechanical shapes without cutting into detail areas too aggressively.

Mipatherm coating

Mipatherm in liquid or aerosol format creates the heat-resistant coating stage for prepared engine covers and mechanical housings.

How to paint engine covers and mechanical housings

  1. 1
    Start with cool, removable parts

    Work only on cool parts and remove covers where practical so edges and bolt areas can be prepared cleanly.

  2. 2
    Degrease thoroughly

    Use silicone remover to remove oil film and hand grease before any sanding starts.

  3. 3
    Key and dust off the surface

    Use the sanding sponge to dull the surface, then remove sanding dust before coating.

  4. 4
    Apply the heat-resistant coating

    Apply Mipatherm in controlled coats and let the coating dry or cure according to the technical information before heat exposure.

Which Mipatherm format should you use?

Spray format for shaped covers

Choose Mipatherm Spray for small covers, fins, ribs and complex shapes where an aerosol is easier to control.

Liquid format for larger housings

Choose liquid Mipatherm where larger prepared surfaces or spray-gun application are planned.

Technical details

  • Mipatherm is the heat-resistant coating stage and should be applied to a clean, keyed surface.
  • Do not coat sealing faces, threads, gasket areas, pulleys, sensors or moving mechanical contact points.
  • Allow the coating to follow its drying and heat exposure instructions before returning the part to heavy service.
Practical suggestion

Keep the film controlled on detailed engine covers. Heavy coating can soften detail and is more likely to mark around bolts or ribs.
