Hello all,
I'm a finish carpenter in the beginning stages of learning to apply finishes for my side jobs. I have a Fuji Mini-Mite 4 and have been using Target Coatings HSF5000 + EM6500 so far on practice pieces for myself/family, with acceptable results (decent for an absolute beginner, but not nearly good enough to charge for it). When I bought the turbine, I was hoping/planning to do most of the finishing on site, since I was primarily working on site at the time. As a result, I planned on caulking and filling nail holes after primer and before the pigmented coats.
Since then, I've shifted to mainly doing built-ins, and doing as much as possible in my "shop" (garage space I can work and store tools in, but not permanently set up like a true workshop), which is also a selling point in terms of being minimally invasive/disruptive to the homeowner. However, this means I would have to prefinish components, including moldings and applied panels/skins, then do any caulking/filling, and then touch-up the finish. I prefer to scribe instead of caulk and use glue/clamps in place of nails wherever possible, and 23 gauge nails wherever they'll hold, but still foresee a non-zero amount of touch-ups in my future. I'm concerned that brushing over a sprayed finish will make things worse, but I'm not confident using an airbrush or touch-up gun without masking, and if I'm masking the whole area off, I might as well bring the turbine and spray the final coat of finish in place.
I'm also considering selling the turbine and using LVLP guns instead if I won't be spraying on site, but that's a topic for another thread.
How do you handle post-install touch-ups (nail holes, caulked transitions to moldings or walls, etc.) on prefinished material?
