I just had the frame blasted for my '69 race car project. I will need to do some welding and fabricating for numerous race related items on it in the upcomming months. I am looking for suggestions to keep it from flash rusting during the time period it takes to accomplish this. So far the two options I have considered are to 1) shoot it with epoxy primer and just grind it away where I need to cut and weld or 2) spray the entire frame down with WD-40 periodically.

The only thing that scares me about the WD-40 route is possible adhesion issues when it comes time for paint. I figured I could just hose it down with brake cleaner to wash away the WD-40 prior to paint. Thoughts?

 

Flash rust can easily be removed with numerous products on the market if you just want to leave it bare for awhile during the work. Assuming you're working on this inside. If painting, epoxy primer sounds good. I wouldn't want to spray the frame down with anything that could affect paint adhesion either.

 

Try Phosphos. I think that's how it is spelled. It is available at ACE hardware and it will protect the frame while your aorking on it.

 

I vote for option 1. Shoot primer now, grind off where you are welding, sand and reprime when the welding is complete.

 

ABSOLUTELY DO NOT DO THIS (before welding on the frame)!

I recently read in a motorcycle magazine that this is a bad practice. Apparently, brake cleaner contains chemicals that will convert to TOXIC gas when heated (I think phosgene).

The author of the article did some welding on his motorcycle frame after cleaning it with brake cleaner. A small pocket of brake cleaner was left on the frame and flashed into toxic gas. He inhaled it and was in the emergency room for days. He mentioned he is lucky to be alive.

I tried to find the article, but I think one of the guys in the office carried the magazine back to the barracks.

 

That it only the case with chlorinated brake cleaner. I use non-chlorinated.

 

I recall that was mentioned in the article.

 

Best stuff out there but its expensive.

I know this is some one elses product repackaged but I can't remember what it is.
