I had to look around several places before I could find condiment bottles basically like the ones they have for ketchup and mustand at hot dogs stands. For some reason hardly anybody stocks them, I called 4 differant resturant supply shops and none of them carried any..
They carry some at Bed Bath and Beyond, which have a kinda of flat top with a snap on and off lid, they are only 8oz bottles so they are on the small side. Sam's Club had 32oz ones with a pointed spot hot dog cart style. (the pointed spout
really helps with measuring out small amounts)
A lot of makers apprently don't add caps on their spouts for some reason, not sure why as I know that ketchup BBQ sauce etc shouldn't be left open to air all the time...
I'm sure you can track them down on ebay or with online vendors.
Here's some from ebay with caps
Make sure to pick up a couple small plastic oil funnels to help pour the large containers into the squeeze bottles as it helps with spillage. Just make sure you use a seperate funnel for each resin half or you will get ruined/ cured resin if you share the funnel for both halves.
As long as they have caps you can store the resin in the pour bottles indefinately as moisture won't get in and wreck it. Just make sure when you go to shake them up you keep a finger over the cap or you'll spray resin all over.
In between casts I've left some of my resin in these bottles for weeks or even a couple months and had no problems, it does settle a bit but that's the same with the large jugs.
I also do a simular process with the silicone, I have several 64oz containers (.5 gallon) with a snap top lid on them that way I can use them as opposed to the heavy gallon buckets which are a pain in the butt to control the flow on. The fridge cooler containers have a pour hole that helps regulate how much you pour so it's not like a tidal wave of silicone pouring over the buckets really wide mouth. The lids unscrew and are wide enough you can fit a paint stir into to mix it up before use.
Helps avoid a lot fo overspill and mess.
