Hi

You are likely to be familiar with etch primer (black paint) but this useful product also has some audio applications. It can be painted with a brush or sprayed and is 'self leveling' properties, similar to that of Hammerite and is almost as tough with regard to being scratch resistant.

I have known about the product for years but never kept a supply in my workshop until my old friend Tyrone "Dustbug" Momberg re-introduced me to the product's usefulness.

A few months ago, I needed to make a coverplate with an IEC cutout for a pre-amp and wanted the job to look good and the plate to have a similar appearance to the pre-amp's black casework.

Enter Tyrone with a little tin of etch primer and a brush. We painted the plate with a brush, fitted the socket and within 1/2 hour bolted the plate to the pre's rear and it looks just like Rotel made it like this.

Some years ago I made a new wand for a Micro arm as I ran out of headshells for it. The wand was made from an r/c helicopter's landing gear with an sme-style socket up front.

I initially anodised the new wand and left it like this for a few years.

Today, it got a few brush strokes of etch primer and this is the result.

So, if you need to touch up a black box of audio gears, go black etch primer (no connection with Dulux ;D).
