🙂Bonus tip🙂 A playing card, or cut piece of plastic from a milk jug/soda bottle...Make a GREAT tool for blending the filled edges without finger streaks... Wrap 1 layer of paper towel around it and it makes a flexible sanding block/spatula that will spread the filler in the groove while forming to the areas on either side Without leaving any finger streaks..And since it is flexible (but not too flexible) you can get great blending areas, and it won't dip into the seam you are filling the way our fingers can sometimes.. Depending on how big of a piece ya cut can allow for super small or pretty wide blends, and gives a great leveling effect because it spreads the pressure over a smooth area like a flexible spatula (but with A LOT more control than a spatula would)🙂 Hope that made sense😄

is that just for quick seal and modeling paste or does it work with foam o too?

[@MistahFox]

I've been using foam clay to for seams, and I could never figure out how to get it smooth before sanding, but I now I know extra water and folding is the secret, thank you!

[@TristanMaker]

No problem! :)

Hi. Don't you need to prime your helmet before doing all this ? Thanks to answer

[@TristanMaker]

Nope, normally it's better to fill the seams first and then prime. So once the primer is on, you can see if you did a good job at filling the seams, and you can fill them once more if they're not perfect yet. :)

I'm new to this. Do I seal the foam then work on the seams or vice versa? I'm working on Vashs arm from trigun stampede

[@TristanMaker]

In most cases, I would work on the seams before sealing the foam. This will give you a uniform surface to paint on.

I wanna ask. I dont have a heat gun and I cant find it in my country. can I use a hair dryier? Can I use a hot glue to stuck peices together?

[@TristanMaker]

You can definitely use hot glue instead of contact cement, as long as you glue small sections at a time and you hold them until they cool. I would not recommend using a hair dryer, most hair dryers can't get hot enough to form the foam. If you can't find a heat gun, try amazon, they have a good selection. You can buy the cheapest one and it should do just fine.

[@SnowDayJ]

Which of these do you prefer?

[@TristanMaker]

The liquitex is my favorite since it's a bit easier to sand smooth.

[@quiggloproductions803]

Can you use these techniques on cardboard helmets?

[@TristanMaker]

It's better to use wood filler, bondo or spackle on cardboard.

[@MossNada]

Hi there! I can only find the normal paste where I live - not the light version. Can I ask what the difference when appplying is please? Thanks!

[@TristanMaker]

It does the same job, but the "light" version is just lighter in weight so it keeps the weight of the final build down.

[@MossNada]

@@TristanMaker Ohhh lol Ok that makes absolute sense. I wasn't sure if it affected it in some other way. Thank you so much for getting back to me :D

[@speedythesnail2235]

Might be a dumb question, but is it possible to use school glue if you’re on a tiny budget?

[@TristanMaker]

School glue might work for sealing the foam, but not for filling seams.

[@speedythesnail2235]

@@TristanMaker Good to know, Thanks!

[@emimatsuno]

cant i just cover it with worbla to hide the seams? :D

[@TristanMaker]

You totally can, if Worbla is in your budget.
