From Wikipedia, regarding Sodium Hydroxide (Found in purple cleaners) Strong bases attack aluminium. Sodium hydroxide reacts with aluminium and water to release hydrogen gas. The aluminium takes the oxygen atom from sodium hydroxide, which in turn takes the oxygen atom from the water, and releases the two hydrogen atoms, The reaction thus produces hydrogen gas and sodium aluminate. In this reaction, sodium hydroxide acts as an agent to make the solution alkaline, which aluminium can dissolve in. This reaction can be useful in etching, removing anodizing, or converting a polished surface to a satin-like finish, but without further passivation such as anodizing or alodining the surface may become degraded, either under normal use or in severe atmospheric conditions.
I'd be interested to see if the shop can do that. I thought the dash roll-down procedure was required for upper hinge replacement. I have a '98 Dakota service manual. The dash roll-down procedure is in there should you get stuck.
This thing is going to fight you the whole way, it seems! Still pulling for you Jeremy! There are several threads and tutorials on darkening panel lines here on the forum. I found some good info using the Google site search method.
The Daisy mags from the AMT '63 Impala are all four the same depth. I can't tell for certain the depth of the Daisy mags in the original photo. Two mags are flat on the back side. The two other mags have a long axle stub on the back in the old AMT style. I tried mightily to take photos, but every one was too blurry to be of any help.
I received my order today, Randy! Thank you for the fantastic service! I highly recommend ordering from Model Builders' Warehouse. The Clearly Scale engines I ordered are downright beautiful. Well cast and extremely smooth. Excellent level of detail on the engines. Thank You Randy and Jeremy!
