Hey Adam,
Neck finish is a slightly different blend. In general i've had less issues with neck coats than body coats. Sounds like you have Dingotone MkII which is a bit more forgiving and no real need to ultra thin coats.
These blisters are totally normal. I get them all the time. Once each final coat is cured, I just wet sand lightly (1500 grit or 200 grit) and in one direction to get it level before applying the next coat. Kinda feels like 1 step forward and 1/2 step back wards each coat, but you get that with any finish, even tru oil. Last coat you should allow at least 21 days curing time, then lightly wet sand to level and polish to your expected shine.
As wazkelly said, we threw out the use of steel wool on DT due to adverse effects in the humidity.
DT has no solvents to aid drying time so it just takes longer, as a general rule i leave it at least a week before wet sanding and applying the next coat. Humidity does make each coat take longer to cure...but you get there.
Mate its looking really good. you should be proud![]()
