Hi all. i have finished 3 1/48 scale planes in the last month, today i went to show a friend my wonderful skills and to my shock i found that all 3 have in various spots white patches. i have had this before and am sure its the dullcote, however i cant workout why?. i make sure i use several light coats and the model is clean.
what can i do to fix this? i was told to give them another light coat and that should cover it. am i doing something wrong with the dullcote or preparation?
