Flexible Drywall Corner Tool & Trim for Tight Door Frame Gaps.

DIYers often find it challenging to finish drywall in tight spots, like the 4-5 inch gaps next to door frames. Traditional taping and mudding can be a real pain and hard to do neatly. A paintable, pre-molded trim piece designed specifically for these narrow, awkward strips could offer a simple, clean, and professional-looking solution. This trim could be L-shaped to create a new corner or have a flat profile with finished edges, maybe even with a built-in channel for caulk to ensure a tidy seal against the frame. This would align well with the user's idea of using trim and caulk. For those who still prefer taping and mudding, a specialized, highly flexible, and miniaturized corner taping tool could make the job a lot easier. Revenue would come from selling these specialized trim pieces or the micro-taping tool.
