I prefer automotive glazing putty...I only use that now.

Squadron green tended to chip along the edges....I did not enjoy using it.

Bondo Glazing Putty seems to work great here as well.

I believe this stuff is lacquer based and sticks beautifully to plastic.

Talc and CA for me, nothing else comes close. Mixed right it never shrinks, dries (cures, actually) fast and is easy to sand, plus it scribes well and holds a sharp edge

So, how do you actually apply this?  Do you mix the CA and talc before applying!  

 

Thanks!

Yes, you put a little pile of talc onto abit of paper or aluminium foil, then drip CA onto it. You then mix it with a toothpick or similar until you ger the consistency you want then apply it to the joint. The more talc, the easier it is to sand, but it is not as strong. 

 

Within two minutes of mixing it will be cured and hardened, so use small amounts at a time and if you want use tape on either side of joints to reduce the amount of sanding. Also, while it is curing it will gel, and you can use a knife to cut any excess away. 

 

Hope this helps
