A few months ago I decided to showcase my 1/18 model cars with my newly-bought 1/18 acrylic cases, and decided to affix the cars to the bases with Blu-Tack. Originally I didn’t think much about the method, and my mother said there is no better alternative, so I just let them be that way for several months. However, now I’m worried that the Blu-Tack would remain in the tyre treads after staying that way for such a long time, and I couldn’t remove them after taking the cars off the bases. It seems my fears are confirmed as well, as I find it quite difficult to remove the cars today, despite not pressing them into the Blu-Tack very hard when affixing them before. So I’d like to ask would double-sided masking tape be a better option, if the method must not damage the model or the base (thereby ruling out the possibility of drilling a hole in the base for screws, because I don’t have a lot of cases to assign one case to one model)? Also, is there any way to remove the blu-tack adhesive that was stuck to the treads of the tyres?
