I need to share my luck. So I have an assembly table, essentially a beefed up version of Norms worktable. For the top I had a 3/4" piece of mdf coated with Poly, poplar edge banding worked well untill this weekend.
We had a party for my son's b-day, after which I put the styrofoam coolers (thought to be water tight) on the bench and was going to put the extra drinks back in the fridge the next day. Next day comes, coolers were slowly leaking, and the water seeped into the top where there were scratches, and where the screw attached the top to the torsion box, leaving 1/4 inch swollen mounds in the mdf. Tried sanding it flat when I thought table was dry, but 2 days latter and the mounds are now divits.
So i figure maybe I will do a new top, formica and mdf, which with BORG pricing for the materials and contact cement and tax will be about $80. At this point I start looking for other options, I found a company that sells sheets of HDPE (white cutting board plastic) and PVC for sign companies, marine appplications, etc. Long story longer, I was looking for a thin sheet of HDPE to top my bench with (1/8" or 1/4") figuring it is just about indestructable, 2 minutes later the guy shows me a cutt off he has, 3/4" Seaboard marine grade HDPE (Higher grade HDPE, UV treated, nice slight texture). I had it cut to my necessary size of 44" x 54", $100 out the door . I can safely say baring the house buring down I will never need to replace this top again, Once I get it installed and route the edges I will take a couple of pics.
