Frame wax touch ups


Recommended Posts

So I've got this Daubert wax for frame touch-ups as my work has taken me to the rust belt. I'm just wondering if I need to wire brush the rust spots away first or if I can just rinse the frame off and apply the wax over the rust spots once it's dry? Any metalurgical engineers want to chime in? Much appreciated!

That’s the GM process.

 

Daubert does say it can be applied directly over active rust, so you can do as much or as little prep as you want. I would at a minimum get any of the lose flakes off and clean the area. That’s how I do it and it works fine. Touch it up often and it stays looking good.

I have the surface rust spots too, with coating cracking off.  
 

WTF ,  can’t GM paint a frame correctly after all their years in the biz.

 

So annoying

 

Wouldn’t mind as much if my 2015 Denali already had not had:

 

new trans at 14k

2 fuel pumps

3 of 4 MRC struts

2 GPS antennae 

new exhaust system 

replaced failed lifter

new radiator

new condensor 

numerous sensors 

fan blower motor

an injector

serpentine tensioner

 

prob more, I can’t remember the whole f’ing stack of repair invoices off top of my head.
