| Howdy barry, Thanks for the kind words. Actually I use both, just depends on what i am cementing at the time. I have found that cyno is good for parts that you dont want to have to hold together for a long time....ie....joining two halves of a fuselage. However, it is not good for clear polystyrene in as much as it will cause it to "cloud". I have even found that by mixing abit of starch or even baby powder will "thicken it up abit" which is great for filling gaps. I learned this trick working with "lock-tites" Black max while employeed in the transformer components industry. We used Black max to fill 'pin holes" in components insulation which, if left unfilled, would cause the parts to fail, thereby ruining a perfectly good transformer lol. We used to mix some of the epoxy "powder" with the black max (which is actually cyno) and it became a paste or almost a putty depending on the mixture. It still sets up fast like unmixed cyno, but will fill a gap really easily like a putty. You only need some sort of spatula to apply it with. have a good day, greg |
