Thats a good idea, but in my case I can't do all that. Number 1 would be, once the primer is sanded off, it would create a little lip, causing me to sand a lot more then I would want to.
Don't touch it on a hot humid summer day with bare hands. It will rust by the next day. I usually cover everything with WD40 for a few days. I use WD40 on my welding fixtures also...Bob
Yea, WD does it for me. I spray my chassis jig down every once in awhile and my bare chassis stuff after welding. It usually is quite awhile before the chassis is ready for paint cause it has to get all the final assembly stuff fit and brackets welded. Basically it get's completely assembled and then taken apart to clean and paint.
I have a few peices that are waiting to be painted, was curious if anyone had any tips to prevent rust ?
WD-40 ? Grease ?
90blackcrx,
Walmart makes their brand of spray paint called "Colormatch" and according to the can directions and the company that produces it Rust-O-Leum just cannot compare. In my experience I believe it! I use it clean as well as surface rusted metals. It covers mill scale and I have seen no rust issues even after being out in the weather for several months. No primer is required. Awesome!
I know the WD or Tri-Flo penetrant works well to prevent rust. However, this paint is not very expensive and performs better than anything I have ever used from a can.
Any dent, pit, or surface defect weakens the material. All cracks start on a molecular level where the atoms are misaligned (i.e. a dent, rust pit, manufacturing defect, whatever). This is the reason you want a weld with the least amount a bubbles or illregularity. However, most of the time you need not worry because 99% of the time these defects (or surface quality as it it referred to) are accounted for in the strength rating of the material. If you want a more scientific explanation I can reference some books for you.

walmart also carries there own brand of wd-40 in a black can that in my expereance workd better than wd-40 at everything and at $0.94 a can ya cant go rong. as a penitraiting oil it is great. I also use it on my welding table to keep the surface from rusting light coat and you are good to go.
thanks for the help

hope i helped

keep in mind if useing it on your welding table wipe the table down after you aplie the oil as it is flamible. dont realy want to leave puddles of it around or put that much on.

General trivia: The "WD" in WD-40 stands for "Water Displacement" It was invented for the USAF to spray down the ballistic missiles in underground silos to help repvent corrosion due to the constant condensation.
Of course, naturally it works great on firearms, fishing reels, tools, you name it.

wd-40 is not ment to be used as a pentrating oil, from my understandings atleast.
Thanks for all the suggestions guys, I do use a rust-oleum product but that happens way down the line.
