What should I build?

It's not a block of resin , just a few cm . Check out 1/72 KV-2 abandoned in water by PLASMO on YouTube

If your going to try resin for the first time go small. Ask me how I know. Resin is expensive, smelley and gets very hot which can distort the kit if your not carfull. However, it can make an exceptional dio. I was thinking of picking up some fiberglass resin from Walmart to see if its clear enough after drying.

As far as what to do next, Goldhammer is right, it depends on what your looking for. Inproving your skillset, reaching out of your comfort zone or just having fun with something easy.

 

MC- might try contacting a wood boat builder or company to see what they use for glass coating.  Most everything I have found on the box stores/parts houses tend to have a brownish cast to them.  I have seen several cedar canoes covered in glass that is clear and glossy.

Sorry for the semi-hijack.

Casting a block of resin of any size is not really doable. It works much more successfully to model the surface with a piece of glass or plastic, adding texture with resin, acrylic gloss medium or nom-silicone caulk. Make a shadow box with the tank underneath.

If I make it it will be 1/72 , and it will be a first for me , never made a diorama before just a vignette , never used resin either . I wanna try it though

The 1/48 offerings might work out, can use "O" gauge model rail stuff to accesorize....

Tamiya made a 1/35 KV-2 back when. It wouldn't be a bad choice if the quality of the model tank isn't the main point. Except it's BIG.

EDIT: NO WAY! $ 117 on eBay! Looks like it'll be Hobby Boss/ Trumpeter.

FYI here is the Trumpeter KV-2 if you are interested

They also make a nice 1/35 one also

A lot will depend on your skill set and what/how long you want the build to go on.  Are you wanting to build on skills and try new techniques?  

Out of your possibilites, the KV build may be the way you go, (IIRC there are KV-2's in 1/35, so you may bump the scale up) but that is a chioce only you can make...how are you on a dio setting with groundwork and water, along with whatever damage the KV shows?  Several people here are very good with water effects and are usually willing to help if you get stuck or aren't sure.

All comes down to what you want to take on and the time invested.
