Typical 'Roden' decals - easily cracked and chipped and reluctant to conform over curves!!
This is one of the reasons I tend to always mask and paint crosses and roundels; plus I enjoy painting and hate using decals. But I've never painted over Aviattic decals - do you have an opinion about whether doing so in instances like this would be ok?
Applying masks then painting is possible over 'Aviattic' decals.
I did this for the model in the link below.
The main thing is to make sure the 'Aviattic' decals are fully adhered to the model before applying masks.
I add a small amount of PVA (white glue) adhesive to the decal water when applying the decals.
This helps to stick and conform the decals to the model.
Then apply a clear sealing coat over the decals.
When applying the masks lightly press just the edges of the masks onto the decal, not the whole mask.
After painting carefully pull the mask away and at a shallow angle.
Doing this should release the mask without lifting the decal underneath.
Then you can clear coat seal the painted surfaces and apply whatever weathering you desire,
