Trust nothing, test everything, and even if you tested it, something will ruin your day anyway. A pen I used to draw up the door panel lines is now bleeding into the final coat of glossy clear. Even the red Tamiya paint is bleeding a bit because I went way too heavy on the clear trying to get a smooth finish.
To be clear for the accident report: The pen lines are bleeding because I didn't test it with the clear coat. The red is bleeding because I significantly overdosed it with solvents from the clear coat.
