Plast-I-Weld, whats the best applicator for it?

I'm not familiar with this system but it sounds like in might be related to things like Tenex-R  and other liquids.

What about using a fine or semi-fine paint brush.  When you're done the bristles would be hard but they should be flexible again the next time after a few seconds.

I've started using an old fine tip paintbrush as well. I tried fine needle syringes but they seem to drip unless you keep the needle pointing up. I also tried one of those applicators that have a glass tube and very fine needle that are supposed to work on capillary action, but I didn't find that it reliably picked up the glue.

I have the Flexi File Touch and flow but I have hardly use it. Just seems like loads of hassle filling the applicator. I have a couple of old fine paint brushers and that has worked perfectly for ages.

Tamiya glue bottles have very fine 'nylon-y' type brush in the bottle lid, I use that, then refill with MEK, Plasti-weld etc,  got a glass tube thingy from Deluxe, but don't use it much

I agree ;

For over forty five years I have been using the tiniest paintbrush I could find . As to the stiffness after use .Wash it in a little Dawn and water and rinse well and you can glue or paint to your hearts content !

I've always used a drafting/ruling pen for these kinds of adhesives, something like this:

The little wheel gives you great control for the amount of adhesive you want to use, and the sharp nibs give great accuracy for placement. And since the nib assembly is metal, no worries about solvent eating it. They're available at most art supply stores and many craft outlets.

You're using MEK?  I hope you have a lot of ventilation.  That's not exactly the safest liquid around.  My wife would sometimes have to use that stuff at work back in the day and sometimes she couldn't remember how she got home.  Woke up with a headache sometimes.  becareful with it.

I use this system for about 99% of all my gluing. I can get exact glue delivery for solid neat joints. Instead of describing how to load and use it watch these clips:

Draw the tool and play with the angle, the steeper angle the more liquid it will dispense. It it clogs then simply put the tip back in the liquid which will clear the clog in a couple of seconds.

Man, does this irritate me! I've bought a couple of these things over the years, usually just sold as the applicator itself, and NEVER did I know you have to have a suction thing to fill it. I could never how to fill the darned thing up! I actually sucked on it like a straw, and got a mouthful of modeling glue once, and that was the LAST time I ever tried using it. They really ought to advertise that you need "The System", and not just the applicator. I honestly didn't even know anything about it.

I was talking to the company rep during the 2012 Nationals and he showed me how to load the darn thing. Once you master the tool you will love using it. Consider the glass tool by itself as a replacement in case it's dropped and breaks.
