Letter 5069 Etching primer for Chrome to enable paint to adhere ?. I am restoring an antique car and having trouble getting paint to stick to the background of a newly chrome plated badge despite lightly scuffing it with 600 wet paper. Can anyone tell me of an over-the-shelf product I can purchase in a small quantity to etch or prime with, for adhesion of my paint? Help! Ray Charest
. Hydrochloric acid, available everywhere as muriatic acid, will easily etch the chrome. Be very careful of over etching and you will need to very careful of dissolving the chrome completely if the acid is undilluted. A fine airbrush with an abrasive will provide a good mechanical surface for adhesion, and there are many precision airbrushes around that will accept fine carbide or carborundum abrasives. Again, be careful and use a stencil mask to help avoid damaging your item. Dale Woika
