[Vwdiesel] Front struts?

[Bud]

I'm getting ready to overhaul my front end.  On the list it was 
mentioned to use an air impact gun to loosen/remove the top strut nut. 
My question is, after installing the new strut, should I use the air 
impact gun to tighten the top nut, or will it cause internal damage to 
the strut?

Thanks,
Bud
