I have this stuff it works for some things but not all , I does not dry clear , you put it on liquid then the uv light cures it , very similar to what dentists use for fillings

I sell this stuff at my hobby shop. I doubt the bond will be strong enough for ramps unfortunately.

I have some too. I've yet to find something that it holds well enough to make any kind of reliable bond.

would say crazy glue would work better

It's too brittle and will 100% fog clear plastic. My best advice, is get a liquid cement that actually welds the plastic. Something like plastruct. I haven't personally dealt with broken ramps yet, but I've been selling plastruct glue for ages. It bonds most plastics including acrylic, co-poly, styrene and abs.
