Using TRIM in SQL SP

I think what I am needing to do is pretty easy I just cant figure out the right syntax and where to place it.  I need to pass a string to my stored procedure.  However it doesn't like characters like . / or :  .  But if I put them into square brackets it will work.  I am going from a form on an ASP page to SQL 2000 through a Stored procedure.  My Data Types are all  VarChar.  I am planning on using the TRIM function to add the [] and then to remove them in SQL unless there is an easier way.  Any help would be appreciated. Please let me know if you need more info. 

Exapmple:

strTime = Request.Form("uTime")

strTime = "[8:28:00]" if I hard code it with [ ] I don't get errors. 

strSQL  = "exec sp_insertStatus " + strType + ", " + StrBuildno + "," + strVer + ", " + strProc  + "," + strStatus + "," + strEta + "," + strTime + "," + strDate + ""

My stored procedure is

CREATE procedure sp_insertStatus
 @vType varchar(20),
 @VBuild varChar(20),
 @vVer varChar(20),
 @vProc varChar(5),
 @vStatus varchar (20),
 @vEta varchar(20),
 @vUtime varchar(20),
 @vUDate varchar(20)

as
declare @vBuildID varchar(9)
if EXISTS

 (
   Select * from tblBuild
 where type = @vtype and BuildNo = @vBuild and ver = @vVer and processor = @vProc
  )

    Begin
set @vBuildID = (Select pk_buildID from tblBuild where type = @vtype and BuildNo = @vBuild and ver = @vVer and processor = @vProc)

insert tblLabinfo
    values (@vBuildID, @vStatus, @vEta, @vUdate, @vUTime)
end

else
   begin
    insert into tblBuild values (@vType,@vBuild,@vVer,@vProc)

set @vBuildID = (Select pk_buildID from tblBuild where type = @vtype and BuildNo = @vBuild and ver = @vVer and processor = @vProc)

insert tblLabinfo
  values (@vBuildID, @vStatus, @vEta, @vUdate, @vUTime)

end
