They charge so much for new cars and they rust like garbage, absolutely no pride in their work. if they had as much pride in their work as you do in your work we would not have this problem.
Needle scale, power wash and blow it off with shop air. Than apply por using your preferred method.
Nice summary
I appreciate your time & incite. I had my car undercoated for a year and a month. I commute to work & had deer blood & chunks underneath, so I had the undercarriage washed at the car wash twice. Will all of that blood need to be removed before getting it undercoated again or will they do it?
What state are you in if people want to have you do the undercoating.
Unbelievable new cars can’t come from the factory with good rust protection.
Wouldn't it be nice to have a car lift
Her. 4runner in the salt belt. We sometimes go off-roading in winter / fall after car has been sprayed, so lot of mud sticks to the undercarriage. Would you recommend washing that off. Knowing that fluid film is applied for the winter season and the salty roads ? Gr8 videos btw.
Question: would torching rust before applying a rust converter and painting help? Asking because I want to bedliner the floor of my car. And the car will never see winter… occasionally rain… what do you think?
So I've been noticing surface rust on my 1-year old tacoma in Dallas. I have seen other tacomas and toyota vehicles a few years older here with NO rust at all. So I'm pretty annoyed by that and have been attending youtube university recently and your info is definitely the most helpful. The single best bit of info that I just learned here, which really surprises me, is that you can apply these something like fluid film over surface rust and that will totally stop the rust. I thought rust was basically a terminal cancer that you had to root out one way or another. So, based on the fact that my rust is very, very thin surface rust, I plan to just apply fluid film over it and call it a day. Huge win. THANK YOU
