Does metal with paint still rust?

Question

Also, does any type of coin rust?

Answer 1

paint will protect metal from rust as long as it was sealed right..

generally speaking if painted metal rust it is because the other side is not painted... or a chip was taken out of the paint and then let to sit in the air for awhile which allowed water to work it's way under the paint....
but if you take any metal and drop it into paint and let it dry it will stay rust free for as long as the paint is on it..

all metals rust.. i believe coins are made with a mixture of metals and coated with a 3rd type of metal... there are many different types of rust.. from the red rust. to white and black rust as well...

I think coins get the black rust on them over a period on time.. but only when not in use....that is something to look up

Answer 2

if you ever been up north and seen a car thats had a huge rust hole in the side or multiple little rust holes on the body somewhere. rust happens in the metal paint does not protect metal from rust. Rust inhibitors or poly urethene coating protect from rust. ever see a rusted/corroded penny

you should are trying some paint remover on the wall if it really is straight forward brick. would confer with the stain sort's internet web site and ask them. at the same time as employing stains one needs to combine the stain now and lower back to save the pigments from settling. once you've truly some gallons or 5 gallon buckets those must be intermixed and the bottoms checked to be convinced the entire settled solids were mixed up. at the same time as spraying use the unique tip and rigidity. Too enormous of a tip and intense rigidity will consequences in intense overspray and waste. i take great factor about a diaphragm airless pump to apply stains and sparkling finishes provided that those enable the pump rigidity to be dialed all the way all the way down to 0 then develop to pass nicely with my software desires. preserve a broom in a unmarried hand to spread out the intense purposes. I absolutely have a variable speed drill motor with a paddle rigged to a 5 gallon pail to carry stains continuously mixed as I spray. earlier than refilling i take great factor about it to combine the stain in different fives earlier pouring some in. there is now no longer a lot you're in a position to do with regard to the darker stained sections except you want to ought to strip it off. some fencing comes with a confusing area and gentle edge. The confusing area will take in additional suitable stain so will be darker. it ought to must be superb if one edge is darkish and the different lighter.
