Krown vs Fluid Film.....or none at all?

[Jakerex]

I’m only considering these two products, and I’m not doing it myself. 
 

Anyone have experience with these products? Can you recommend one or the other for any reason?  Does it work?  

I have a fluid film place about 20 minutes away and a krown place about an hour away.   So either would work for me. 
 

Does this stuff piss off your mechanic cause everything is a wet mess underneath or does it dry eventually?

 

Does it drip on your garage floor or driveway?

 

Thanks in advance for your thoughts and opinions.

I’d go with Fluid Film.  Lots of YouTube vids about it and many positive reviews.  It is drip-less.   Some people complain about the smell but I think it goes away after a bit.  It stays wet, never dries.  In fact, if it feels dry, it’s time to reapply.  It is not a one-time coat.  Needs to be done annually.  
 

Just be careful about applying too much product on the frame.  It will soften the factory wax on the frame.  If you over do it on the frame, the wax will slide off in sheets or when you pressure wash it, it will potentially blast off the soften wax.  This isn’t a Fluid Film specific issue.  Any oil based rust inhibitor product, over done, will soften the factory wax.  
 

I know it is counterintuitive but avoid pressure washing the undercarriage after Fluid Film.  The pressure wash can remove the Fluid Film.  
 

Some mechanics will hate it I guess.  Some might appreciate not having struggle to remove a rusted nut/bolt years down.  I had the GM 2” lift done 1 year later at the dealer after I had it undercoated, no complaints from him.

Curious also, I almost pulled the trigger on the Fluid Film and have been doing research for a while. I will likely will go for the CRC myself based on the Project farm (YouTube) video on coatings. Subbed for info.

 

The second link has a guy that does a post 1 year evaluation on FF and has some good information. 

 

Seems like Fluid Film does dry off and becomes easier to work with but don't have first hand experience myself. Hope this helps and good luck with your search.

One additional consideration is if they are cross compatible. If you move or don't have the Krown place available, I believe more shops support the FF.
