So what your saying is use resin to fil the void. What about bondo, will that work

 

yeah you could use short strand or long strand bondo...I wouldn't use regular bondo...of course that would be a hell of alot more expensive that using resin and sand like I already suggested

oh god...don't be a hack and don't use expanding foam AT ALL...what you do it glue around the seams of the cardboard and make sure you have a perfect seal and then get some fiberglass resin and mix it up and then add it to a whole bunch of play sand and pour it in...you could use straight resin but it would be weaker and way more expensive since sand is cheap. If I have learned one thing in SPL anything hollow in the box is BAD

or and after you are done that it would be even better to take the cardboard out completely and cover the fiberglass/sand area with bondo and sand it till its smooth with a series of flexible abrasive discs on a angle grinder

CONCRETE NO NO NO THIS SET-YP IS HARDER

you have 2 boxes?
i was looking at it for some time
i LIKE IT/THEM AND I'M AN SQ GUY

 

So I tried both bondo hair and resin/sand....

Bondo hair was alot tougher to work with, what a disaster that was... resin/sand was soo much easy to mix, apply (cause it pours easily), and fills the gaps much better.

 

If you lay a plastic bag in the gap, or line it with saran wrap or something like that, THEN fill with concrete or resin/sand or whatever, you can then remove the cardboard and buff off the stuck plastic.

 

lol isn't that what I said like 10 posts ago?
