I have the opportunity to get a polypropylene storage tank to use a sump. However, I'd like to put some baffles and seal up some bulkhead holes that were put in it. Can some one point in the right direction as to what glue/solvent and material I could use to accomplish this?

Thanks!

If it is just baffles you want to add and patching holes you can use acrylic and silicon, or the weatherstripping method to make baffles movable.

Silicon does not stick well in applications that will have a great deal of pressure, but it works fine for baffles.

To do it correctly, the baffles have to be hot air welded in place. Look in the yellow pages under "Plastics, fabricating, finishing and decorating" (or something to this effect), ask them if they do hot air welding - they'll know what you're talking about. You can also buy a cheapo hot air welder from companies like Harbor Freight

Way overkill, IMO

I think I'll take Jame's advice. I'm trusting him w/ my tank after all. :)

When was the last time you tried to glue something to polypropylene? Using silicone on acrylic is one thing... polypro is a whole different game :)
