[urq] Dipping vs Blasting

[83Urq at code2use.com]

Thanks to everyone for thier great replies!

I think I have decided to do.....neither! :) 

I am hoping to buy a chassis rotisserie from http://www.accessiblesystems.com 
and do a combination of chemical stripping (brush-on kind) and localized media 
blasting. The rotisserie will be handy for removing the undercoating, and also 
later in the project for doing brake lines, fuel lines, exhaust, suspension, 
etc. and I can use it for my GTI and any other projects that come my way in 
the future. Although it will probably take longer to do it myself, I think 
that stripping the car this way will let me learn more about the condition of 
the car first hand, as well as deal with problem areas in a more surgical 
manner. Wish me luck!
