This is a thinner version of widely acclaimed Flexy 5K glue, thanks to its formulation this glue can be easily used via capillary action. Glue is also more looper friendly than thicker types. As the original Flexy 5K glue forms flexible bond that withstands much more punishment than classic brittle CA. This essentially means less accidentally lost parts and more productive and enjoyable work as there is much less need to reglue vulnerable parts. Extended open time (150% the standard CA) allows for good positioning of the parts. You also will be able to glue tricky parts (both PS and metal) that produce tension. Flexy is less aggressive and more easily removed when necessary it doesn’t “eat plastic” as classic CAs.

Photo-etched parts are a great way to add detail to your models, still in isn’t always easy to position and affix them them well. General use CA bonds too quickly to position the parts well, forms brittle bond and attacks plastic. Flexy 5k is the opposite of standard CA + it comes in 25 ml bottle!

What’s the best technique for precise application of the glue?

Dispense a portion of photo-etch glue on a piece of styrene, glass or a metal sheet, never on cardboard as it will absorb your glue. Have a 10 cm long piece of straight brass or steel wire ready, its Ø 0.5-1 mm. The wire will act as your renewable glue applicator. Dip the tip of a brass or steel wire in the blob and then touch it to a PE part or the model itself. Bring the parts together. That’s that! Now cut the tip of your applicator wire with your trusty modelling knife or better side cutters to start anew with a clean tip. Small parts can be held with tweezers and dipped in the blob without resorting to the wire.

I have dispensed a portion of the glue as per instruction, how long till it becomes useless?

A blob of glue is good about 30 minutes after it was dispensed. It gets thicker overtime. For best results and to conserve your glue dispense smaller blobs to always have a small amount of fresh glue at your disposal.

I have misaligned my PE part and want to reposition it!

Slide the tip of your hobby knife between the parts to separate them. Once the parts come apart scrub the remaining glue in the same manner, try sliding the tip between the glue remains and the part from the side, the glue will give in. PS may need some sanding after the procedure. We didn’t recognise a need for debonder, Flexy 5k is modelling friendly.

​I want to create a stronger metal to metal joint!

To make a metal to metal joint stronger simply sand the more demanding parts such as tank skirts (schurzen) barrels etc. By doing so you will achieve the following:

remove the patina,

remove possible dip coatings some PE manufacturers apply over the frets,

give the glue better adhesion thanks to the altered surface.

Use 600 – 1000 grade paper and sand only the spots that will accept the glue. Joints created this way are up to 50% stronger than smooth, not sanded metal which can be problematic if unprepared. When you sand your brass fret you will see the change in colour, it’s a sign of a well prepared surface.

Please note: even apparently pristine frets are covered with some patina, it’s natural for the brass to form a layer of it over time. If you can’t see it it doesn’t mean it’s not there same goes for dip coatings.

There are problems with the joints I’ve created!

Fingerprints and any other residue don’t help your cementing! Make sure you degrease surfaces and sand the more difficult metal parts if necessary to remove brass patina and/or dip coatings. Degreasing can be conducted with simple dish washing fluid for plastic parts. Metal can be degreased with dish washing fluid but you can also use more aggressive chemicals such as acetone which evaporates very quickly and requires no drying. We advise you degrease metal parts with VMS Styrene Cement (standard type) which is a solvent blend and degreases better than basic chemicals (pure acetone).

​What’s the shelf life of the glue?

Opened bottle can last 1 year no problem even if frequently used. Unopened easily 1.5 year and more provided it’s stored in a room temperature: around 20 °C, best temp. for storage is around 15 °C. Store in a dark place, avoid direct sunlight.

    Had a lot of trouble using various CA glues on photoetch over the years, but recently saw this being used in a video. Tried it and it works perfectly. Brilliant. Wish I’d know about it before. Glue photoetch parts very easily (even complicated shapes). Would recommend this.
