Going to strip the underside of the Mustang and paint it with Chassis Saver... Any words of wisdom? I was going to take 3inch cookie and go to town...

Have fun... :lol:

Seriously though, the only real thing I can offer is if it's pretty dirty under there to make sure to thoroughly degrease it and remove all undercoatings and such before taking a grinder or sanding disc to it. You'll just load up the paper/brush and smear it around and go through paper like crazy if you don't.

Also, I hope you have a rotisserie, because even on a lift it sucks balls. Shit will get in your face and your neck and shoulders will hate you afterward. On your back under jackstands might be slightly more comfortable, but I hope you have a mask on of some sort because you'll get more shit in your face than you can imagine. :)
 
Oh and personally, I would spray a couple coats of the chassis saver rather than brush it if there's any rust you're sealing. I personally feel it gets in all the cracks/crevices/pits better that way and seals it more thoroughly.

Yeah, honestly if it were me building a car as nice as yours and there was any rust at all under there, that's what I would do too
 
Thanks for all the responses guys... Honestly I really don't want to media blast it... I want to do it myself and learn...


Carl I'll text/BBM you later...
 
i did just a frame with cookies and a little stuff. That sucked. Media blasting would be faster, better and possible even cheaper depending on how cheap you get supplies
 
Reiko i know the feeling of wanting to do it yourself, But I can almost guarentee if you do.. Before your done with the project you will say to yourself "damn, I wish I would just got this media blasted."
 
You aren't gonna "learn" much prepping the bottom of your car. I would get I blasted and paint it right. I know you want the car done asap but this little but of extra work can save you a ton in the long run.
 
To be honest prepping the underside of a car by hand is probably the worst way to go about it, media blasting will give you better adhesion and you have the ability to spray an acid/etch prime before your chassis paint. But if you want to do it by hand I would start with a can of aircraft stripper.

Are you wanting to prep the underside for a show quality smooth appearance?

Just to get the dirt and grime off before I apply the Chassis saver... That way it looks halfway decent...
 
I did this with my car it was a nightmare when i do the next one I'm going to see if someone has a rotisserie and either blast it myself or take it to my bud after i see how much he charges me.
 
use a HOT water pressure washer soak the entire underside with kerosene then use the pressure washer, it will remove everything but the paint, even the factory undercoat will come off
 
I used the power washer and went to town, then sprayed POR15.

This is my old yellow coupe. 1981 body. Didn't strip it though. Any surface rust, or whatever.....it got painted over. That's what Chassis Saver and POR15 do...sticks to rust better than bare metal.
