So, when i purchased my rx8 it had water in the tail lights. I fixed it by put the new gaskets in place. Before I put them on I tried rinsing them with soap then drying them with no luck. Then I tried using white vinger then letting them dry once again it didnt work. I was told later that its best to go vinger then rinse with distilled water but i didnt do that. My lights are starting to look crappy so i need some help. I also though of drying them differently then my little contraption but I honestly cant let them dry for more then a day or 2 at max. I also attached my drying method if that helps any.

 

I tried all the same stuff as you with no luck. Someone mentioned that swishing rubbing alcohol around in the light would do the trick because it evaporates so fast... DON'T DO IT! I caused the chrome coating to disintegrate which turned into a white powder. I should have just lived with the few water spots. I ended up getting a new housing for $90.

 

lol I actually used the spot free rinse stuff you can put in a dishwasher. It worked really well.

 

this is a known issue with 8's do some searching here, and you'll find a DIY fix for that, i believe it requires a small 1/8" drilled hole, so the water can properly evaporate. i believe it's on the top of the housing.

but don't take my word, search the forums and you'll find it.

 

Same here. DON'T DO IT!!!!! I did the same with a backup set thankfully. I was restoring them from being smoked. Polished the outside perfect, then decided to put the rubbing alcohol, or maybe it was vinegar, anyways, ruined the entire housing inside. What a waste

 

Tint them red and you won't see any water spots.

 

put in distilled water in like 2-3 cycles

 

Im not really sure how drilling a hole is going to fix my water spots but thanks. I guess I am going to have to try the distilled water thing.

 

Try Windex or some other glass cleaner? Cleans spots off the outside well enough. I've used a hair dryer to dry water quickly from the inside so swishing some glass cleaner then heating to dry up residual quickly may prevent more spots by slow drying.

Honestly, I tried a bunch of stuff to keep water out, long term making a number of small drill holes is best so you don't have to deal with it again. I made maybe 4 or five small holes in the black area on the bottom so they are unnoticeable. Even after a few days of intense thunderstorms no more water, just a little condensation and that is dry shortly after the rain stopped.

 

I too drilled holes in the bottom black area. After one rain storm , not joking, a fish would have done just fine in the tail light. Talk about embarrassing, some jerk in a Mustang GT made a point to let me know at a stop light. I already knew but had to rush somewhere first and than fix it. After a couple of times of taking it out and drying it with a fan, I got tired of it and just grabbed one of the smallest drill bits I could find at home but made sure it was big enough to let water easily pour out. But I suggest that whoever tries this, not to be lazy and pull the light housing out first before drilling. No issues anymore and it dries at a decent speed.
