I watched this Video on You

I watched this Video on You Tube, great location to add some weight on certain locos, My only beef is with the choice of Adhesive, white glue, the plastic tank and the metal shot are  non porous materials, and although it will adhere well at first over time it may dry out crack etc and fail... Although one could say how often are you going to remove the tank..that said...my choice of adhesive might be a 2 part epoxy like JB weld, a bead of silicone, or maybe rubber cement.. 

Lead/PVA glue combination - swelling caution

HI all,

I second Daniels' caution with using lead/PVA glue to hold lead-shot into cavities under wagons/locomotives or inside boilers. 

See  https://forum.mrhmag.com/magazine-feedback-was-ezines-891776 I've personally never used PVA glue to hold in lead shot. This reaction was first noticed many years ago, initially in the UK but later elsewhere, where several modellers reported brass locomotive boilers had been split by the swelling reaction. The lead PVA glue chemical reaction is irreversible once it starts and can result in the structural failure of models.

This reaction appears to take some time to occur, but when it does... 

Silicone Paint ??

This question came up on the post:

Silicon Paint ?

So who sells it, who makes it, where can I find it?
