I've tried the search function, but after sifting through 10 pages without finding my answer I'm just going to ask it here:
I've seen/heard multiple threads about coating the inside of standard, thin-wall cardboard body tubes in order to make them easier to clean and a bit tougher. I have tried some different things with varying degrees of success. I'm about to start on a homebrew modular BT70 rocket and I'd like to try some new techniques with it.
here's what I've tried in the past:
- Wood hardener - Seems to work but it is more "fuzzy" than glassy / slick.
- CA - works, but it builds up in 'rings' as you coat the tube. It's also difficult to coat the inside of longer tubes.
- wood glue - Works, but ends up pretty thick. Also tends to pool at one of the tube, requiring constant rotation.
I would ultimately like to simply soak the sides of a foam brush with whatever hardener I'm using, and 'bore brush' the inside of the tube with it. I'm hoping it to be hard/glassy/easy to wipe clean, and drying WITHOUT pooling or requiring rotation.
I have seen 'thinned epoxy' mentioned. Which epoxy (finishing epoxy / laminating resin? 5 minute? 15 minute? Aeropoxy?), and how was it thinned?
I'm leaning toward BSI 20-minute, BSI 30-minute, or ZAP ZPoxy.
Thanks!
