Woody V Posted March 14, 2019 Share Posted March 14, 2019 Looking for tips on tinting Bondic to make formation lights. I tried using epoxy but it's too thin to get a dome shape, it just runs out onto the surrounding surface. Out2gtcha 1 Link to comment Share on other sites More sharing options...

I would think the small droppers of food coloring or some Tamiya clear red/green might to the trick. Link to comment Share on other sites More sharing options...

Woody V Posted March 18, 2019 Author Share Posted March 18, 2019 Did a test and Bondic can be tinted with Tamiya clear colors. It does harden but when I rubbed my finger over it it lost it's shine but a tiny but of clear gloss or Future took care of that.

I was hoping some clear Tamiya acrylic would do the trick. Woody V 1 Link to comment Share on other sites More sharing options...
dmthamade Posted March 18, 2019 Share Posted March 18, 2019 First time I tried tinting was with Tamiya clear paints, even after hitting it with the UV It didn't dry/harden. Tried again after 6mos, same thing but let it sit longer(days) seemed to be OK. Have a project on the go that I might try on... Don Link to comment Share on other sites More sharing options...

If red, you may be on to something because red blocks UV. I used blue and "cooked" that stuff for at least 15 seconds. Link to comment Share on other sites More sharing options...
dmthamade Posted March 18, 2019 Share Posted March 18, 2019 It was red, never did try blue or green... Don Link to comment Share on other sites More sharing options...
dmthamade Posted March 23, 2019 Share Posted March 23, 2019 K, i used Bondic on some formation lights on a Trumpeter P-40F i'm doing. Instead of mixing the paint with the Bondic i painted the well with the needed color, allowed to dry, then used a toothpick to fill the well. Hit it with the light, and checked. Looks OK, but the Bondic felt soft, rubbery, sticky. Let set a few days, and the Bondic did harden ok. Was able to get it to form a teardrop shape, i had to fill two of them twice, but i'm good with the results. I used Tamiya clear green X-25 and clear red X-27.

Don Don, That's interesting because that's exactly why I'm inquiring! How did you make the "well"? Was it already molded into the kit or did you make it somehow? My experience is that you really can't just try to lay it on a flat surface in a teardrop shape so I even considered taking a round brass rod and filing the end into the desired shape, heating it and pressing it into the kit to make a well. Sounds risky so that's my Plan B based on what I see when my formation lights come from Russia. I did manage to find CMK formation lights but those things are insanely molded in a way that I couldn't imaging trying to get them off the "sprue". I've also found that Bondic doesn't harden right away. Even after I let it sit for a few days it still dulls if you rub your finger over it so I put a coat of Future (clear acrylic) over it to seal it. I figure if it's not hard it will gradually pick up dust. At this point, I'm thinking tinted epoxy is still my best bet. Link to comment Share on other sites More sharing options...

The well is in the kit mouldings, they are relatively deep, probably deeper than they need to be. I think if the Bondic is tried on a flat surface it wouldn't work as well. I think the depth of the well and surface tension work to make a nice teardrop shape. Don't think you need much of a well, but I think the edges would need to be sharp for surface tension to be your friend. Sealing the Bondic sounds like an excellent idea, whether gloss or dull coat depends on your weathering of the build. Epoxy sounds like a good choice, at least you may have a little control over drying time. Don Woody V and Out2gtcha 2 Link to comment Share on other sites More sharing options...
thierry laurent Posted March 27, 2019 Share Posted March 27, 2019 Another solution I used in the past: 1. Create a master of your light with sanded plastic (typically from the end of a sprue or a plastic blob superglued on a toothpick) 2. Push that master in epoxy putty to create a well and let the putty dry fully 3. Use heat to soften the end of a colored clear sprue 4. Push the soft sprue end in the well to mold the light 5. Let it cool down 6. Saw the light from the sprue 7. Glue it! Hope this helps Thierry Woody V, Greg W and Out2gtcha 2 1 Link to comment Share on other sites More sharing options...

I've seen a similar method used to make non round formation lights and markers such as the tear drop shape. Much easier to get the shape you want when making the master then plunging it into putty or milliput or the like. Woody V 1 Link to comment Share on other sites More sharing options...
