I have found that the critical part of this etching process is the laying down of a clean, consistent coating of photo resistant paint onto a clean, scrubbed brass sheet. Not as easy as it sounds; believe me. The results so far are OK but not perfect. The paint tends to ball up and sit in blobs on the brass surface. Its also very easy to apply too much paint. Getting just the right, thing and blemish free coating is very difficult. However, I have now found a company in the UK that sells pre finished, coated brass specifically designed for etching. This stuff comes in 250 x 250 mm sheets, 0.3 mm thick and coated on both sides with positive resist film. That means that normal artwork in black and white will work with them. They use a propriety developer and Feric Chloride as an etchant. Interesting.Comment

Looking good mate. Now if Don will get in touch with me so I can get a Golf kit and a Charlie kit from him. Working on the plugs now for a 1/72 Thresher and a 1/72 George Washington SSBN. Don't be hating on this old pink jockey because I do 1/72. The 598 is as long as the Delta. Plus I am making it a split hull so it won't cost $600.00 to ship to you Foster drinking homies. Funny the Delta went from New York to California to Louisiana to Tasmania then to you.Comment
