Thanks mike to check it out and the nice compliment too , appreciated !
Hi Conor , i'm glad to have you back ! Thanks for the great comments on my groundwork , it's great ( in a way ) when you have that chilly feeling if you look at the scene .
To give you a straight answer to your question......the item i used was 100% transparant silicone glue and i've applied it with a silicone gun ( i hope that's the right name for it in English , if not, you may have a good laugh
Nevertheless , please have a look at the picture below and you sir shall see what i mean !
The foam on the water is just some drybrush with white oil paint, don't use any kind of thinner or washes based on thinner because otherwise the silicone will shrink for sure !
Allow me to give you this last piece of advice ; Don't try to rob the bank with it , it won't work
Hoping this was usefull ? Regards
