type of acrylic to repair

[Ugly-one]

I am trying to buy sheet of acrylic to repair / cover few holes on back side of my old acrylic salt water fish tank ,but I donââ"šÂ¬Ã¢"žÂ¢t know which type acrylic sheet was used ( ( did a search on the web nothing came up ). the tank is true view how can i find out is it a extruded or cast acrylic ..any help or information is greatly appriciated

all tanks are made out of cast acrylic. extruded absorbs water and is not as strong as cast. are you planning on cutting the existing sheet out? or just cover the current sheet with another sheet? are you going to put the sheet inside or outside?

im planning to cover existing hole and put one from inside and outside .any suggestions are welcome .

How big are the holes?

there are 5 holes 1/2 inch in diameter ....the back side of tank is 36w X 26 h ..im thinking of glueing a full sheet of acrlyic on the back and glueing a 36w x 6 h from inside and fill the corners with silicon. .

when i got tank, the previous owner had small pieces of rectangular patches on the holes and it looked very ugly ..i removed all the old pieces and i want to have a clean look as possible.
im waiting to get a quote from usplastics sent them a e mail this evening to see how much they want for the plastic.
