To mould the decal apply VMS Decal Softener over the decal and wait 1-3 minutes. The decal will soften and adjust to the surface of the model. You can use a cotton bud to help the decal conform to the surface, perform gentle tapping motion. Do not get the softening fluid on the paint job as it can dissolve the paint (true for any softening fluid brand). If the paint reacts with the softener simply introduce a bit of water to neutralise the softener and leave the paint be, it will revert to its original state. After 24h seal the decal using VMS Varnish HD. Due to the multitude of decals on the market and varying thickness of carrier films always check if the softener is compatible on a spare decal first! (
If the softener is too strong you can dilute it with water in 1:1 or 1:2 water to softener ratio and still use the fluid with your decals. This problem is rare though.
