In Topic: Removing scratches from a dome port

04 August 2009 - 09:08 PM

Ok--If I can do it, seriously anyone can do it. I appreciate the tips from past posts, such as the need to use the sandpaper and micromesh on the entire dome and not just on the scratches, and that the dome would look like a diffuser but would get clearer and clearer as you use finer micromesh (thanks for the photos from an earlier post). Take your time and read the really easy instructions included in the NC-78-1 kit. It took me over 2 hours but I was being very precise. Although it doesn't look brand-spanking new, it almost does. I am very happy with the results and am ready to use it in the galapagos next week.

SGL I used the liquid solution (Novus) and it worked, although from re-reading this thread I bet the micromesh would've worked even better. You WILL get a huge sinking sensation with the coarser starting point...don't panic, don't rush, and don't skip steps. That was my one mistake - I was so terrified by the 'scarification' the coarser solution made that I quit too soon and went to the finer stuff....only to finish and find that some of the big scratch was still present, so I had to start over.

Just resist the urge to 'focus' too much on the problem area (which I assume is a "2cm , deep" scratch") or else you alter the curvature locally in a way that might make a focal ripple. Time yourself, take rests if you feel like you won't have the endurance to keep going rather than risk sloughing off on a step...and trust in the force. :)



Thanks sealifeprints and rtski for the encouragement. I should have done this a few weeks ago in case something goes wrong. I'll probably do this tomorrow morning! I'll report how it went when I'm done

I leave for the Galapagos in 8 days. I have about a 2 cm deep scratch on the 8" acryllic dome port. I have the micro-mesh NC-78-1 kit. I sure don't want to mess this up because there's no time to get a replacement dome before the trip. Can you tell I'm looking for reassurance...So I have to do the entire 8 inch dome port? I'm planning on doing it after dinner tonight. Is there anyway I could really mess this up? The instructions and the previous tips seem pretty straight forward? Is it really that easy? I'm paranoid to do it.
