Temporary rust protection for recent metalwork repairs

Post by Oldmogman »

Could any bodywork experts advise me whether it is worth me spraying recent metalwork repairs with WD40 until the weather is warm enough to spray it with Dinitrol (which needs to be applied at a minimum of 15 degrees)?

The repairs I want to protect are quite inaccessible, so I wouldn’t be able to wipe off the WD40 prior to spraying the Dinitrol, and I wondered if there is a risk the WD40 might compromise the rust-proofing abilities of the Dinitrol?

Depends where you are but it’s 14 degrees this Saturday in the South East. If you’re Scotland maybe around August time !!

Don't spray wd40 over anything you intend to paint which can't be degreased.

I use etch primer, which is good for a short-time, but I have in the past applied primer then lacquered to create a water proof barrier.

Then sand back when you need to perform more work

Or warm the panel with a heat gun, stick the dinitrol in some warm water or get a space heater going.

The temperature instructions are vague at best. Aslong as it's not significantly colder I can't see much difference
