Looks great. I like the changes you made to your hardscape as well. Are you doing dry start?
Yes I am dong the DSM method kind of funny because I too started in the car world as you can see by my and your user name and when I first saw DSM you can imagine what I thought they were talking about ha ha.This is also my first time trying dry start "crosses fingers"
As far as using plasti dip I have used that stuff before and was never really satisfied. Not saying it wouldn't work because I dint try it for this. Also there is a large difference between being waterproof and being submersible. Damn universal solvent.
