Need formula to bring out metal stamped letters


Recommended Posts

Hi there
I have an old camper from the late 1970's. I located the VIN number on the trailor tongue, but due to years of weathering on it, the number is very light and almost not readable. Is there anything that I can put on it to make it easier to read or bring out the numbers better. Many thanks to all.

Much care must be taken while doing it, but yes...to raise worn numbers stamped into metal use strong acid, be prepared to neutralize the acid as soon as the numbers show or you'll lose everything. The acid will eat away the less dense material leaving the denser compressed areas of the numbers.
