I had excellent results masking a 4-color wavy camo job with this Frog tape on flat and large curved surfaces (1/32 MiG-21) while using MM enamels cut heavily with lacquer thinner, but I find that the trick is to burnish down the edges really well regardless of the tape type.
When Frog tape first came out I suspected the “ingredient” that prevents seepage must be something that reacted with water. So I take a clean paint brush dipped in water and go along where it is stuck to the model. I do this regardless of the type of paint I’m using.
Having said that I cannot confirm that this makes one bit of difference.
if you want an almost direct substitute for tamiya …pick up a roll of ‘shurtape cp-60’
tamiya tape is manufactured by Kamoi Japan… not 3m
I’ve used it just recently on painting a wall. Much better than blue tape. I used latex paint.
