Body sand blasting or acid dipping Options

When prepping a car for sandblasting, what is the common thing to do with the aluminum tags in the front trunk and door pillar?

I suppose the second question would be do I acid dip the car or get it sandblasted?

I've been thinking about this. the 911 chassis that we get media blasted come out ok but our metal guy still has to do a ton of work once we get them back. Cut out all the swiss cheese metal that was hidden with paint and bondo, remove a lot of the epoxy primer to do the metal work, ect.

Recently we sent out some tubs to an acid dipping co. and I'm waiting to see the results.

I know the paper heater tubes dissolve in the acid.

Here's my question. what if I replace those tubes with another one by snaking it through the openings on each end of the long. Similar to what is done with oil lines on a 6 conversion or water lines on a Suby. I know the lines will have a smaller ID than stock but they could be thin walled (no high pressure like an oil or water line) so maybe the ID is big enough. If I can get enough hot air through the tube, I wonder if a large, insulated tube is needed. Even the heat on my 4 cylinder car, without a working electric fan, is HOT in the winter and unlike my daily driver, I'm not driving my six on the coldest days of the year. I'm really just looking to stay warm on the >40 degree days.
