could I use chalk ( not blackboard chalk, but celence chalk) as a response type?
Try it. Let us know. 
That makes more sense.
yup.
People have used it before. If I remember correctly they didn’t like it anywhere near as much as flowable or gasket maker silicone.
sealent caulk works great.
ive tried it with two differnt kinds of caulk and it is too ippy for me silicone gasket maker red or blue is what i generally like
cool, guys, i ll try it ans tell you how it worked!
