Update,
this morning, the model has recieved its first coat of paint, however, im stuck again
during the cleaning of the airbrush, i noticed the nozzle was spraying crooked due to damage to thze nozzle.
i tried looking for a replacement but it appears spares for revell basic airbrush set are hard to come by. at the current rate i would not have one until august/september at best (revell 38373). and im not gonna buy a whole new airbrush just for the nozzle.
in gonna try to make a fix, but for now, it doenst look good
EDIT: i just ordered a new pair of Airbrushes with 0.2, 0.3 and 0.5mm nozzles at the same cost as the replacement parts.
should arrive next week.
