I just acquired a used 4 year old Siverado Desert 18x33 AGP that is very good condition but would like to replace a few parts while it is disassembled. Specifically the previous owners had screw decking onto a few of the top rails, I would like to replace these since they have screw holes in them. Also, two of the verticals were below ground and stained. I may as well do these too since the rest of the pool still looks pretty new. Thansk for any info you all may provide.
