Just picked up 4 trust/omori gauges (boost, water/oil temp, oil pressure) and two of them are fogged up from the inside out. any ideas of how to fix this? I was thinking about sinking them in a bowl of rice overnight or maybe blasting them with the heat gun any suggestions or past experiences?



^ not mine but you get the idea

 

Sink them in a bowl of rice for 24 hrs and that should do the trick.

Don't do the heat gun... You will very likely warp the plastic.

 

Update... Ended up taking them apart. I uses a small screw driver to pry the ring around the outside on the front of the unit took some time but I was careful enough not to make too much of a mess of it then the glass and rubber seal popped right off no problem. A quick Polish of the inside lease and it was back together then just bent the ring in to seal it off no problem
