Right answer, if the finish will not permit steaming.
It is called a drop fill. The idea is to overfill the dent. Use medium viscosity CA. It may take more than one dose. After the first dose, spritz with accelerator. Wait ten minutes or so for the chemical to evaporate. Wipe clean. Repeat.
When sufficient material has built up and cured it is time to level. Files are the best tools for this job. Carefully file until the fill is level. Then switch to a razor blade scraper.
The razor blade scraper is a single edge razor blade on which the edge has been turned into a hook. Take the blade and run the edge across a HARD steel rod at a slight angle to draw out the hook. Hold the new tool between the thumb and forefinger of both hands while pulling the blade across the leveled fill toward (or away from) you. Continue until the fill is just proud (.002" - .005") of the surface.
Switch to 600 grit wet or dry paper on a hard block. Use a few drops of water to float the grit and CA away from the repair. The area that you are sanding will end up larger than the original dent. That's o.k. because you will continue to work up through the grits until the gloss level is correct. Use rubbing compounds to buff out. If a high gloss is desired (not in this case, just to be thorough.) use a course of finer and finer compounds.
An alternative to traditional abrasives is Micro-Mesh. The grits start at 1800 and go to 12,000. For a matte finish, you will not use all of the grits. For a perfect high gloss, use finest compounds and a show glaze to finish.
