Was thinking of having some trailing arms powder coated. Got two estimates from local shops. Cheaper one claimed that they didn't need to put a primer coat on before the finish coat as it wasn't necessary, the finish coat adheres well enough by itself. More expensive shop claimed that an epoxy or polyurethane primer was absolutely necessary. Any advice from the past experience out there?
Thanks, Andrew B. |

If you run sticky tires (as I assume Andrew does), rock chips are a major issue.
I just dug out rocks up to one inch on a side out of my rockers. My formerly pretty swing arms are well blasted at the pivot area. The etch primer under the top coat is holding up well, tho. A before pic... Attached thumbnail(s) |
