Any one on her ever use it? I keep getting a white, greasy residue around a brand new water manifold . I ve
got no drips , but I keep having to wipe it off. It’s in a dragster with a remote meziere pump. First time I’ve ever added this additive. Only thing I can figure .

I have used it for years, never have had any issues. Also have used Lucas super coolant from time to time, pretty much the same thing IMO but its blue. I use store bought purified drinking water from the grocery store if it matters

I’ve found Lucas Super Coolant to be excellent and this year I tried Rislone Hyper Cool Super Coolant recommended on DRR and think it’s an excellent product also. Both need to be used with “Tap” water (I use softened well water). I just drained the water out of the drag car, looked clear and replacing with 50/50 for winter protection.

I’ve used Water Wetter several times 15+ years ago, following their directions and always ended up draining rusty water at years end.

About the past 4 years I've been using VP coolant improver during racing & use 50/50 antifreeze for off season storage. I don't have any rust-colored water when draining anymore.

In the past, I've used numerous different additives & used the 50/50 for off season as above. I always had rust colored water when draining.

never had a issue.
Is the residue on the outside?

Yeah

The water wetter or Lucas Cool will have a greasy residue to it if leaking.
