To imbed a You Tube video:

copy everything after the =

Then paste that on your post, highlight it and press the You Tube icon - must be in advanced edit to get to it.

Presto:

Installing an embedder is the way to go, I still can’t get it to work.

Muriatic WILL etch the metal. It needs to be diluted a lot to be safe for the metal and then it works much slower than his results.
If you are going to use it, have a large enough tub to submerge the entire piece to avoid etch lines like I got soaking my fenders one side at a time. The etch will be uniform and if rough enough, supply the "tooth" primers want to grab the metal (substrate) That would eliminate needing to hand sand with 80 grit.

Muriatic Acid is a wonderful thing. :)

I don't see the Youtube icon on my desktop computer. Does this only work on phones?

He mentions a stronger muriatic acid and Lowe's sells it I believe but he uses it full strength in video.

I didn't watch the whole thing, cause I can't stand all the hype and BS. If it is already diluted, it may be fine, but don't leave it unattended for long...keep checking it often and remove as soon as it is clean.

I would never use Muriatic acid on stamped steel panels, especially if there are any welded joints (such as at the bottom of this front valance. You will likely end up with paint bubbles a couple years after paint is applied.

JMHO that it is not worth the risk.

I have used it (full strength) previously on cocktail shakers years ago and primed and painted them afterwards with no issues to this day.
