acrylic weld on

[Europhyllia]

what were the two weld ons to use to fix small cracks (but NOT gaps) something 3, something 40 maybe?
one was faster but illegal in California. The other worked just as well but a bit slower

3 or 4 will soak into a crack and can seal it. 16 is thicker and can be used on the outside. 40 is two part and hard to get - they only sell it in the gallon size the last time i checked.

Thanks! It was 3 and 4 I was thinking of

You can order 40 in pint size but you have to do it online. 3-4 is water thin and could possibly fix cracks, i would use 3/4 on the crack then patch it with 16 on the inside and outside. Best option would be 40. HTH

I may still have a tube of #16. Email me if you need it.

It's just an ultrafine crack. You can see it. But nothing leaks yet. And it's on a cone so patching from the outside would be awkward. I am hopeing weldon 3 will just fuse it back together and not require anything weird on the outside. I kind of use these as matching lava lamps (isochrysis bubbling, etc.) on my end tables so I want them to stay pretty
