STRIPPING!!!! |
| I wanted to get the car down to bare metal for a complete restoration. It seems to get harder and harder to find companies to media blast cars. |
| Chemical dipping is another option. I am opposed
to chemically dipping any car or metal with overlapping segments. I have
seen a few restored cars which were dipped rust from the inside out. I
have also seen freshly restored cars take a corner on the first drive
only to have chemical stripper run out of corner right across the
fender.
Problems with chemical stripper: -Paint stripped in areas you cannot re-coat -not all excess stripper neutralized -stripper and neutralizer left in between layers of metal and channels only to ruin your day some time in the future

Media blasting is my choice in bare metal restorations. Some one will always warn you that Sand can warp body panels. Well hot air can warp panels if excelled hard enough and what must be understood is who is doing the stripping and the context of such.
The problem with sand is if done by an "Industrial Stripper" who does not do cars they will likely ruin panels. One must also consider the person stripping industrial equipment stands a good chance of messing up a body panel regardless of what he strips with.
I have seen strippers who could strip most cars with sand and I have seen people take plastic media and ruin a panel. Know who is doing the work and know their back ground. My local sand blaster will not sand blast body panels and there fore I would not ask him to. He knows the limitations of the guys holding the guns.

Having said that there are many forms of media to "Blast" a car with; sand, plastic, glass, dry ice, etc. In my area I do not have much of a choice. The last car I did was crushed glass and I found that to be a good compromise.
The Pantera was soda blasted (baking soda). While it did get the paint off it did not get the surface ready for primmer. It was touted that the panels would not rust up after soda blasting but I saw little difference.
Soda is very mild. You can blast a small part and it will not remove things like serial numbers. You can blast parts such as carburetors still assembled and wash them when done.
They said if the car was sand or glass blasted that it may not be possible to remove the paint and primer with Soda blasting! Shows you how sand/glass can rough up the surface making paint and primer adhesion very strong.
It did remove the paint but left rust and the surface was not ready to be primed. It was one of the few options I had as I could not blast the paint off with the equipment I had. I could follow up after the paint was gone as you will see.

| Body panels were primed with Etch Primer! | Wow, don't under estimate the work to get to this point! |

| Water was my number one enemy. I would
blast for 10 minutes then wait for the compressor to catch back up. I
fought and fought and fought water in the line. Finally I bought an air
dryer from Harbor Freight and I fought water no more:

| Getting the right equipment is key. First I
use a zip up painters suit from the hardware store (hooded). I wear
cowboy boots( or some type of strapless boots). Helps keep the sand out
of the shoes/boots.
Breathing protection is a must. Sand is very bad for you when breathed. Sand abrasions in the lungs cause sores which do not heal which leads to cancer! So yes, a mask! Ear plugs help keep sand out. I use the thin disposable rubber gloves. I tried the hood with the glass and the screen which is suppose to deflect the sand so it does not etch the glass. It did not work well for me. I found the best solution was to purchase cheap disposable goggles from Harbor Freight; 3 for $4 (cheaper on sale). I wear them for about an hour then toss them for a new pair. I still wear the hood, but the hood has no glass. Finally, you need to work out your own method of cleaning up acceptable to your spouse! The sand will follow you. I shower in the shop and it still takes a while to get the sand out of everything! |
