Progress on several fronts today. Injecting internal fillets in the 3" MAC Zodiac using a syringe and plastic tube - less messy than the others have been. Finished repainting a red stripe on the LOC Hi-Tech nose cone, it had peeled when originally unmasking the full-airframe-length stripe, and repainting an aligned same-width stripe has been harder than I expected. And got another coat of white on the Estes Starlight, hopefully good enough to call done!
