MARTINSR Buy Evercoat and you won't have a problem. Don't think it's just the date, move on up to Evercoat.

lets cut it up I use body fillers every day...in fact we have been tring different ones because it seems the formulas seem to be changing as the rage I used years ago acted tolaly different than the one I buy now. I find that most of the fillers stay somewhat tacky untill you cut the top layer. Yes it clogs paper. The thing that I noticed is the different brands do it differently. Now if you dont mix up the filler before you add hardener you will have some problems drying also.I put mine on a shaker then let it settle. Metal glaze is also bad for tackyness after drying. By the way people, 3m owns evercoat so dont think your getting something different with evercoat products!!As far as fiberglass resin goes..it wont cure if there is oxygen present hence the wax additive if your not going over it again with glass.

I haven't used all brands (obviously) but the difference may be that some are prone to dry more slowly, due to differences in the formulas. Cold weather, of course, would slow it down even more.

If it's a small area, you might try a heat lamp... but don't get it too hot!






Over Five day's at 90* is a long time to sit and wait... I wonder how many more days it will take...


The reason you can glass over that glass ,,Is because it doesn't have wax added..The one with the wax added you will have to sand in between layers..

lets cut it up Wow people...I am sure glad this isnt a discussion on what is the best lead blend for doing body work. For God,s sake...it just body filler, and you pay for what you get!

Also for a golf ball size of filler you only need the amount of hardener the size of a pea. Make sure its thoughly mixed and not marbelized.ie hardener streaks. Apply in 1direction. This controls uniformity and consistancy of the filler on the surface. Wait for the filler the fully catalize. Harden. On average it takes 15-20 mins for a good cure at 20 degrees cel. If all this dont help change product. It might not be good anymore. Peroxide hardener has an average shelf.life of 2years wheree as filler is good up to1-2 if it has not been opened.


You must not have read ever post.... This is not the problem...
Did you ''EVER'' try this stuff... I had three guy's try to give me this stuff after they realized it stay's tacky for over a week.... And I do know all about how to mix it and how much....Now if you didn't use this stuff.... I really don't think you know about it.... And by the way you posted here... I don't think you did use it... But that I don't know...... ''NOTHING'' Will change what everyone is saying about this.... It doesn't get hard On the outer layer... Pain and simple......You can go mix it for him... IT WON'T GET HARD..... Now if this was one guy saying this.... Well !!!! Just maybe he didn't do something right.... But it's being said by ''EVERYONE'' that has tried it....

mr4speed My jobber just got a few gallons of USC special lite (grey/black can), gave it a shot at only 14 bucks a gallon, and honestly cant tell the difference from the z-grip that I usually use. Problem is that once he gets another batch in the price goes way up.

And how about the Evercoat "Glaze coat" with a white hardener, OMG you can't see when you mix it. I am told the Glaze coat and Metal coat are exactly the same with just different colors. I like the Glaze coat color but with blue hardener.

NEW INTERIORS I was always told it's all the same hardener....
The color was added to be able to know when it is mixed all the way.... Did someone lie to me about this ???
