STEP 1 Paint Removal

Remove the valve cover and other engine parts you wish to paint. Remember to mark which spark plug wire needs to return to its original connection, this can be done by wrapping and numbering a small piece of masking tape around teach wire.

STEP 2 Preparation

Using paint stripper remove all the old paint, grease and grime bringing the parts down to bare metal because that is what the new paint will adhere best to.

Spray on a light coat of paint stripper and wait 5 to 10 minutes for the paint to dissolve and bubble. Brush over with a metal wire brush and clean with soapy detergent. Residual paint can be removed with sandpaper.

Degrease using isopropyl alcohol on a clean, lint-free cloth and allow to dry.

STEP 3 Painting

Using even strokes, spray left and right, starting just before the paint area and finishing just after the paint area to ensure even coverage. Because your valve cover and trim are uneven surfaces spray at different angles to ensure full cover.

Apply 2 or 3 light, even coats of primer and allow 5 to 10 minutes drying time between each coat, then using the same technique apply your paint colour.

At this stage, any raised metal lettering such as logos can be scraped back to bare metal using a craft knife.

Finish off with 2 or 3 coats of clear coat and allow to dry.
