Hello all,

I have a metal CPU which I filanny got the overlay and most of the adhesive off...wow, what a pain that was.  My question is.  I can see some of the grey metal but there is a black film over most of it.  It is not sticky anymore and if I scracth at it I get to the original metal.  My question is is it safe to take a sander to it?  I did scratch a piece on the underbelly which was painted black and it did come off but it was scuffed.  I plan on painitng it anyways (or maybe an overlay...haven't decided) but I want to make sure this isn't a mistake before I do it.

If it is okay to sand, what grit should I used?  I have 80 and 120 on hand.

Thanks a lot for your time.  I have attached a pic of the CP.

That picture was halfway through the process...all the adhesive is gone...just a FYI.

Thats a labor of love right there... good luck. I wouldn't mind taking a sander to it - you possibly can use a solvent to make sure all the glue and residue is gone. If you sand, I'd start off with some 100 and see how that works.

not to be a killjoy as you are obviously having a lot of fun with this project but a sheetmetal worker could have knocked you a new panel up for about $15.

dcsgguy:

I know, but it is an old Tempest Cab and I want to keep as much as the original stuff as I can.  Plus it is sort of fun to restore something that was beat up and make it new again.
