Tamiya markets three different strengths of decal setting solutions under the Mark Fit label. The most aggressive of the three is the Mark Fit Super Strong. It is meant to deal with the most reluctant decals such as those supplied with Tamiya’s own model kits. This video compares the performance of Tamiya Mark Fit Super Strong with Walthers Solvaset for the application of a current Tamiya decal supplied in their P-38J kit.
