Advice on Material to use when adding on to plastic boats

Post by Razor17019 » Tue Jan 10, 2017 10:31 am

I need some help on a project I am starting.

I am trying to convert a boat into a PBR MKII.

I want to add a deck on top to put in my forward MG ring.
What material is easy to cut, paint and glue to plastic?

Any advice, links or suggestiong would be helpful!
Thanks,
Razor

Plastic on plastic is typically best so Styrene should work well. I also break my "adhesives" into two categories:
- Dissolving
- Bonding

Adhesives that disolve work by reduce a layer of the source material into a slurry of it's original liquid form for just a moment. When you attach it to another object, it's that slurry that hardens into the pits and texture of the target. This is why plastic on plastic works so well with plastic model cement (disolve) when you use it on both the source and the target. The two slurrys mix together and harden with the two objects essentially becoming a single new merged plastic object.

Bonding adhesives like CA glue work more like liquid tape. They do _not_ dissolve the target and use the pits and texture of the source and target material to adhere to and when the slurry hardens it's connecting the two items together. This approach is less strong because it's really just like two sided tape. The source and target are still independent objects held together by the hardened glue.

Combining the two can be really strong. Dissolving the source and target plastic a bit, and then mixing in some CA glue has made the strongest bonds for me so far.
