Got any underbody rust protection tips?

[ballistic]

Going to have the car up on the lift in a few days. Wanted to do some protection while im under there. Its reasonably clean for its age and mostly just surface rust. But i want to take some steps to keep it that way.

 

I am planning to clean away any surface rust and use  Bilt Hamber SC-50 for cavities. And for exposed metal surfaces (such as W brace) i will use BH Dynax-UC or maybe BH Electrox, not sure which is  more appropriate.

 

Just wondering if others who have done this have any tips for areas to look out for, or must do's while im under there? Or any advice on products etc

Thanks @zelda, im not sure how this didnt pop up during my searches. Took some tips away

 

I have about 4 hours on the lift. I could go back the next day if needed, but thats about it. I only wish i could do what he does in the vid.

So cleaning out your arch lips if you can is a good idea too because they like to rust on the arches, also the rear arches fronts have these stupid plastic cover trims which collect muck/ water and start to cause rust issues like pictured, so I’d get in there and have a look at that, here’s a few pics of mine after I treated them

I only have the time available. so gotta do what i can. Thanks for the tips.

 

Archs and sills seem a priority then. Will hit the kidneys and whatever else i can.
