What is rtv? I am toying with the idea of keeping my current 180 after I move. I would need to take it apart, buff out all the scratches and drill holes for a sump. Just wondering if this was worth it.Fill it if you can and Check the seams between the panels if the silicone looks white then it is being stressed or pull apart.
If it looks normal then you’re good.
If it looks okay then I would just do a reseal on the inside.
I bought a 220 that the silicone was actually coming out I used the RTV silicone and did a complete tear down and rebuild.
That was in 2009 it’s still holding.
RTV is really good.
Keep us updated on this project P PYRU look forward to seeing your outcome.
