I was hit on the highway a couple months ago and I have some metal damage on my door. It's just a tiny pinch, but it was enough to go down to bare metal. Thankfully, it never rains here. But I would like to protect it anyway in the meantime while I figure out how I'm going to fix the actual problem. What kinds of sealants are out there? Is there something I can just brush on? The spot is very small, perhaps a centimeter in length at the very most. I can take a picture if that helps.

 

Clear nail polish.

It comes off easy enough later to actually fix the damage (nail polish remover), and will keep water out in the mean time, without showing.

 

An epoxy primer.

 

Fix the door, prime it and seal it. (with sealer)

Otherwise, the nail polish idea sounds like a good one to me.

 

I'll go with clear nail polish. I appreciate it!

 

Honestly, I only even thought of it because of a craigslist post. Something about the car for sale having bullet holes that the owner thought looked so cool he used clear nail polish to keep them from rusting. Supposedly, the holes were 3 years old, but the pics showed no signs of rust forming.

Sigh, I spend too much time on the internet...

 

I would Fix the door, prime it and seal it.

 

Fixing the door is not an option right now. I need a good, temporary rust prevention sealant now.

 

^^ ok well when you are ready to fix it then do the above..

 

Priming it with an epoxy primer would also do the sealing job as well... However try the nailpolish i guess

 

Nail polish is pretty ghetto but if it works then hey. I wouldnt trust it for more than a few weeks though. .02
