Painting Diff Covers

Step By Step Guide

Unpainted Diff Covers

Once I realized my factory differential covers where not going to hold up to the riggers of off-roading I decided to upgrade. I purchased the Riddle Manufacturing diff covers. 

They are known to be one of the strongest diff covers around fabricated from high grade iron. Plus, they are designed to have a lip free smooth transition. Which is beneficial when rock crawling. The covers came with a bare finish that allows me to grind, prime, and paint.

STEP 1

Grind the surface smooth. I work in a fabrication shop so there are plenty of tools and experience to help me with my Jeep needs. We work with steel, aluminum and bronze all the time so the guys helped me get started and gave me some really good tips for grinding.

STEP 2

Clean the surface. I used Acetone which you can get at your local hardware store.

STEP 3 

Prime the covers. The best primer for the bare finish on the steel is an automotive self etching primer. I read, once the primer is sprayed on, a tack cloth should be used. I was a little hesitant doing this, but it worked awesome.

STEP 4

Spray on the final color at least two to three coats. Mine happens to be Sumptuous Purple.

Step 5

Paint the accents with black model paint. Then 3 to 4 coats of clear coat.

Some folks suggested I powder coat my diff covers. I decided for the regular old rattle can. This will make repairing the scratches and dings much easier. There could be several of these repairs since I like to crawl on rocks.
