I'm not sure where you're getting your info from. Weld on #4 and #16 both require a couple of days to fully cure, sometimes more depending on the application and environment. Both harden beyond workability in a matter of minutes. Weld on #16 is excellent for seams if you can apply it cleanly, but it does tend to goop and string. Using weld on #4 for seams works well but your seams have to be PERFECT, and I mean that. The last tank I built with 3/4 acrylic and weld on #4 I sanded all the seams with an aluminum block and 100 grit sandpaper before joining.

Google the "pin method" of joining acrylic <- I've had by far the best results that way. The first sump I made with 1/2" acrylic failed at one of the seams because I bought into the "just put the seams together and apply weld on #4 so it wicks in".

I've worked with weld on 16, and it's a bit more gooey. Weld on 4 is a lot more fluid. The basis for my statement is here:

I wasn't planning on trying to wick it in by any means. I was planning to use the pin method. I'm not sure there is a better way. The pin method doesn't work very well with 16 from what I have read - thus the plan to go with 4 for seams.

Cool, just making sure! many folks just slap together and pour on the solvent. I did the same thing and it held water for 6 months but eventually the seam split. Sounds like you've got a plan though!
