how long has it been like that?
i sold a brand that did that also. it looked iffy to me.
i found that Goop worked best. i seen it hold up over 15 years no algea under it anywhere silicon cant say that.

The acrylic is a lot more durable and stronger as a center brace than glass. I still felt uneasy with silicon holding it. The manufacture assured me their tanks would hold even if the silicon came loose. And they were comfortable with the silicon. for whatever thatââ"šÂ¬Ã¢"žÂ¢s worth.

Gorilla glue is a single component polyurethane. It is not "glue" per say. It is a VERY LIGHTWEIGHT polyurethane product that has very little strength. I never looked to deeply into it, but would imagine it is a "5lb foam" or less (I would guess 2LB or so). Meaning that fully reacted product would weigh less than 5 LBS a cubic foot.
Gorilla glue works on wood for 2 reasons. Firstly wood is very porous. Secondly wood has a fairly high moisture content. Single component PUs seek moisture (this is what makes them react). The moisture in the air will cause gorilla glue to react as well. Ever notice how it foams when you put it on wood? That is the moisture in the air and wood causing the reaction to catalyze. The more moisture, the more foam. This also means that Gorilla glue must be used on clamped work. Otherwise the glue will expand and cause the two pieces to push apart, making a very weak joint and a mess. However a comination of clamping and hte glue expanding cause it to push into the pores of the wood, creating a strong grip. The pices have to be very tightly clamped to form a very thin layer of glue between them.
If hte wood is to dry and to porous, the glue soaks in, leaving little to join the wood. If the wood is to moist, the glue overreacts and creates a weak joint.
The glue will not work on anything else with any success, don't even bother making a mess to learn the hard way.
MY $.02 cents... gorilla glue sucks for just about everything, including wood! I like good old yellow carpenters glue. Easy to clean up and will last a lifetime in most cases. There are some instances when polyurethane wood glue is usefull, but I honestly don't run acorss to many... and like I said in a previous post, I have pumped millions of pounds of this stuff. I have pumped it in every type of situation from underground coal mining to the inards of dams and power plants, rock quaries, stream beds, geothermal wells, water towers, and a dozen other applications. I used 1 container of the gorilla glue on 3 different projects just to see how well it worked and wished I had used carpenters glue all 3 times.

Man that is an art that has changed. Last blank I shaped was good old clark foam and 4oz glass (silmar resin if memory serves me). I guess everything is poly and epoxy now. Back in my day the epoxy boards were new and SUCKED! Then again my board hasn't seen any hardcore action since Costa Rica in 96 or so (Kind of tuff to surf in pittsburgh). Sadly most of my friends gave up the thrusters for fun boards and nose riders in the last few years, as aging seems to be reality none of use were ready for.
In any case this thread has now turned the corner to depressing me, so it's time for me to excuse myself.

my twinfin hasnt seen water since 82 Purto Rico. i never even got to ride a thurster. right now id love to ride a long board.
go Goop. you wont be sorry, a little runnier than sillicon & dose not dry as fast. it will also stay on your hands for a full day if you dont wear glove.

I tell you what the new boards that are epoxy are outrageous. At 220lbs I can float on a much smaller and more maniuverable board. I tought for 3 years and during my summer on time I decided to build a tank to ride out here on the smaller days. Now my sis is begging me to make my niece one. I've been reading up on a cheap alernative using foam from Home Depot, Glueing it to a stringer, coating it in epoxy paint, then just use standard ole 4oz fabric and poly resin.

too funny Atlanta talking to Pittsburgh talking Corpus Christi about surfing. i think Corpus Christi has it the woust, you have a beach but no waves. :lol: :lol: :lol: LOL

hey it was actually chest high yesterday. Unless it's a storm we typically don't see anything over 5 or 6 ft. Then when it is bigger, most places around here can't hold that large of a wave so it's closeouts all up and down the beach. Surfed a couple Hurricanes in Galveston last year. Fun

Is that EPDM foam safe in a reef tank? Won't degrade or decompose into the tank?
I've got a 30gal glass that I want to make my new sump but need to add some baffles. Acrylic is much easier to work with than glass when using a dremel to make custom holes/slits/etc.
