I used weldon #4. I have some pretty nice seams for my first time. Out of the four sides of the sump I have together, 3 have only a few tiny, it bitty bubbles and most of it is crystal clear perfect seam. However, my last seam of the day, developed a bubble that looks like it goes all the way through. It is on the top portion of the sump, so maybe not critical but would like it fixed.
The router table is not DIY. But its miter slot is not standard. So I cannot use some of the regular miter stuff that is available. I have thought about making a new miter slot and putting in a standard T track, but it is getting a bit expensive for something I was DIY'ing *the sump* to save money on. At this point it would have been less to get it made by someone else
