Vents and helium vents are installed. For the vents I used the coating pattern and painted the part with Tamiya TS-30 Silver Leaf. For the helium vents I used 1 mm / 0.04 in styrene round rod, each rod is about 2 mm long at 1/32 and is covered them with a small transparent plastic sheet as shown on the picture below or figure 39 of the 1/24 LM assembly
