[PSUBS-MAILIST] sanded and polished windows

[hank pronk]

Hi Keith,
On windows that were just lightly scratched, I sanded with 600 grit with water then 1500 grit.  It only took two sanding steps.  When there were deeper scratches, I wet sanded with 400 grit then 600, and finished with 1500 grit.  When I had to remove gouges that you would think impossible, I started with 220 grit and then 400 then 600 and finished with 1500 grit and always wet of coarse.  I polished with 3M 05937 compound in one step with a very smooth pad.  I started polishing with a more coarse compound  but found the fine stuff worked in one step.  I polished the windows in a fixture so they did not move around and I could flip the windows over quickly and often to avoid building up heat.  The windows stayed cool with no trouble.

Hank,

What grit and method of sanding an polishing did you use on the windows? If you could do a quick tutorial,I at the very least, would find it very helpful.

Thanks

Keith

Today I sanded and polished the windows for Gamma.  I ended up doing it myself because my guy is busy.  It work out great and I am surprised how easy and fast it went.  I even managed to remove some gouges about .040 deep.
The sub was painted yesterday and will be dive ready by the end of the week.
