Cantar Estate 52" 24" round above ground pool 2001

Hi, I bought my pool from Klenswite in Cape May County, NJ back in March of 2003.  It is holding up well with exception of the top rails.  I replaced all the top rails to the pool with your company back in 2010 at a prorated 65% cost.  The top rails are again rusting.  Not all, but at the entrance of our wedding cake steps and maybe four other places.  Would it be possible to reorder another replacement for these at the prorated 65% since it has been 10 years?  I do not wish to replace the entire top rail system though.

I look forward to hearing back from you at your earliest convenience.  Many thanks.  You can also reach me at my cell # 609 425 1809.  Sincerely, Carole Donohue
