Guys thanks for the input. Pelican I have read some of the threads you have contributed on mentioning the interprotect 2000e product.
I have also landed here

After having done this; would you still advice against foaming in the tank and then glassing it? I do plan on raising it using this as my guide

Thank you all for the contribution.
