Window Repair
Lightly scratched windows can be polished back to a state of optical clarity. If scratches or dents are
greater than 0.5mm deep, the window must be replaced due to the loss of structural integrity. For
scratches and dents 0.5mm or less you can repair the window while it is installed on the ROV using the
following method:
1)
Protect the surrounding parts near the area to be worked on. Do not cover any part of the
window, only adjacent parts such as the side bodies.
2)
Using a #1000 sandpaper, buff the scratch or dent out. Coarser sandpaper can be used if
required if the scratch or dent is significant.
3)
Using a #2000 sandpaper, polish the area that was previously buffed with the coarser paper.
Continue to buff until no work marks are visible. The window surface should appear chalky
white at this point.
4)
Using a paper towel or lint free cloth that is 100% free of any sort of grit, rub in a liquid polishing
compound that is compatible with Acrylic/PMMA plastic. Continue to polish until the window
appears optically clear.
