    Good to hear the epoxy resin is recommended here as well. We will try that for my brother's project after we finished installing the suspension from 4Wheelonline on the truck.

    Packing tape works very well. But it is difficult to wrap a piece of foam with compound curves. But don't leave tape marks in the resin once it's all done.

    Fiberglass will bond to almost any surface, including wood, foam, metal and even plastic. For applications such as boats, the fiberglass is applied over foam. This is a fairly easy process that involves adding a fiberglass mat bonded together using fiberglass resin.

    Spackle is faster, creates the barrier needed

    Hi guys, I have finally zeroed in on a technique for giving a protective layer to the foam. Just use a thin sheet of fibreglass and coat it with epoxy resin to form a protective layer. Once this is done, you can use a regular body car body filler to do the finishing work without any problem. I have made few scale models for some clients successfully.

One thing about the white foam is that it melts very easily hence why I'm saying to top coat with plaster or some thing like it to give some surface stiffness
    I understand you.
    when I worked out the costs, the pink foam is just too expensive overall.
    It is ok for small projects.
    Does epoxy resin react with White foam?
    In few weeks, I will have almost all the samples here.
    I will report how the test goes.

Be careful on larger areas especially flat or ones with small curves. if you are putting just a very thin layer of filler heat from curing resin will melt the foam and distort your molds or parts if you just interested in parts.

    Hi guys,
    Thanks for all the suggestions.
    I have kinda solved the problem.
    I coated 3 layers of fillers and sprayed primer and painted. the extra coating works.
    I will also try this product called ENVIRO TEX Lite

    I have used 2 coats of leftover latex wall paint over foam to prevent the resin from melting it. But I was using the glass over foam as the buck... not as a mold. Tried duct tape as it nicely contours over curves but ir wrinkled with the resin over top of it

    Ive been researching this recently....

    I dont know if this product is expensive.
    Polyurethane resin.

    Another is wood glue, (Water Puddy)a kind of plaster, and cheese cloth.

    Plasti Dip might work.

    Mortar and Lowes Latex.

    I would like to experiment with the latex stuff from Lowes and Waterpuddy in the future.

    With other chemicals, make sure you dont mix something that becomes hazardous like how one can suffocate mixing bleach and Ammonia bathroom cleaners.
