Weldon #4 with Applicator Bottle - 1/4 Pint - 4oz - 10308-1 Each

I needed to weld some acrylic pieces together(backing for a fuse/relay box) and this does a great job. If you want something nicer(I used black acrylic), find a different applicator. Just tipping the applicator, the liquid starts flowing out, made a mess the first time. The piece I was working on is not display piece, so I didn't worry about that.I like that this weld/melts the two pieces together versus gluing, gives it a stronger connection/bond. Other than the applicator, this worked great for what I needed it to do.I would suggest pouring back what you didn't use back into the container and make sure it's totally sealed. I left 1/2 of liquid in the applicator, and it evaporated. Applicator doesn't seal well.

Found this stuff is amazingly easy to use bonding pieces of acrylic, but works extremely well. Just remember that some will probably leak through the joint, so put down something (I use newspaper) to protect what's underneath.

Works well but hard to get into the dispensing bottle.

Adhesive worked very well on the plexi. However there are osme issues. Difficult to open can. No way to transfer liquid from can to applicator bottle included. No instructions included. Practice on scrap before you do the final project. You cannot clean up spills so take extra care. As noted by other users, included applicator bottle is very poor. Spend the extra and get some better bottles. Worth the extra money, especially if your project has to look good for a presentation. Once you get the hang of using the liquid, it worked very well on the plexi case I was building. I've used this type of glue before so I was already aware of some of the difficulties. All in all, I would purchase this product again.

I wanted to glue several sheets of Lexan together to make a clear cover display case. This stuff is perfect for this. It is very, very thin (much thinner than water) and wicks into the joint(s). It drips and splatters very easily. One tip that I discovered on the internet is that if you inadvertently splatter or drip some on unwanted areas, DON'T TRY TO WIPE IT OFF. Just let it dry (evaporate) and it will barely show.

It adhered the acrylic to itself very well. Only thing I didn't like was the scarring that was done on the opposite side of the material and the rate of evaporation of what was left in the bottle.

Super thin viscosity, thinner than Tamiya Extra Thin Cement. This works on thermoplastic materials. I tested it out on styrene and it is crazy strong and fast. I also tested it out on PLA for 3D printing it it works on there too. It is *not* gap filling, so have a good fit first.The bottle, much has been said how badly it leaks, and with good reason. There is no seal at the joint between top of bottle neck and the cap. It easily leaks along the screw threads, but there us an EASY solution.5/8" OD rubber O Ring. Put one of these in the cap and now it seals 100%. Done.The steel needle tip can clog if you drag it along a seam for styrene or PLA. I had to clip the tip off as I had no wire that small to clear it. Now that I am aware of this I can avoid it.Bulk cementing sheets of styrene together works fantastic.

You definitely need to practice and know how to use this product. I messed up a few of my acrylic table numbers so overall I would recommend that if you don't have to mess with weldon, then don't.
