wetsanding headlights

for this i went with the following grits of automotive sandpaper and wetsand using water with soap in it to lubricate:

all this sandpaper is $2.79ea at CDN tire.

180 (only if really, really, REALLY bad)
Meguairs Plastx
Sanding block
bucket of water with soap in it
cloth x 3 (1 to keep area wet, 1 to dry area to see your progress, 1 for plastx)
buffer (orbital or highspeed if you have it, if not use cloth)

SANDING (gets as smooth as a baby’s butt)
sand for about 5 minutes per grit in a smooth steady motion, each grit will erase all lines from the previous, so when i got to 1500 and 2000, i used those just a tad longer.

START (look at that pitting and hazyness)

then orbital buffer and meguairs plastx (or other buffing/polishing compound) which removes the cloudy part from all the sanding and leaves it crystal clear. did this for about 15 minutes and really worked it in the best i could applying about 3 coats of plastx.

NOTE: a highspeed buffer would have removed all lines and make it shiny as hell, but i don’t have access to a highspeed buffer. i’d probably go 1800-2500rpm since its plastic and if it heats up it won’t be pretty. move it around alot and stop to feel how hot its getting, highspeed buffing makes alot of heat and if you melt a part of the lens, your ****ed. another trick to this is to use spray water to cool it down, i wouldn’t recommend this way unless you know what your doing and have done it before.

Why 180 grit, thats pretty heavy isn’t it?
yes, one of my headlights was so bad, it looks like it was from a 1990 civic that has never been washed. after this its crystal clear and you cannot see any scratches unless your like 1ft away, then you can see some small lines from wetsanding, this is because i had to go down to 180 grit to get all the pitting out. the drivers headlight was started at 400 and there are virtually no lines at all, but it was replaced at somepoint before, so it was much newer.
