Issue with Evercoat Rage Extreme Body Filler

[7E-Bodies]

 
I'm working on skim coating small areas (like over DP40 epoxy coated lead joints) and the filler is plugging the hell out of my expensive 80 grit paper as I try to feather it all out. I've experienced with larger amounts of hardener (above prescribed) or even slightly lower. I've even used a digital scale to get things exact. Shop is roughly 65°F and low humidity. Even a brand new sheet of 80 grit pills up with "coasters" within two minutes. Light or heavier pressure doesn't matter. I'm leaning towards saying Evercoat is s**t! I've even used several brands of paper on different blocks. Pictured is the Eastwood vacuum block and special paper for reference.

I've found that regular body filler isn't the answer for pinholes/scratches. You want a cream style finishing putty. They dry faster and sand easier as they're a lighter style. Your heat may be a bit of an issue as well. Most fillers are formulated to dry best at 70' or more. U-Pol makes a good one. They're often a goldish colour as well. Good luck

Evercoat is good stuff, either you are not mixing it well enough, not letting it harden long enough or possibly a bad can? I`ve never had a bad can, did it freeze?

Too much hardener

[torredcuda]

I`ve never had an issue with too much hardener other than it kicking off too soon, too little on the other hand and it won`t fully harden.

@torredcuda it didn't freeze. Shop  never gets that cold. I've found letting the application sit overnight before sanding is helping (as mentioned above). Anything over 65F in my shop and I'm burning up so it's seldom warmer than that unless its spring/summer and I have the doors open.

As mentioned, an overnight cure should help as will proper hardener amounts. As for temp, your shop, your choice, but I'd at the least use a heat gun (carefully) until it's warm, not hot, to the touch and as a retired old bodyman, I've slung my share of mud, too.

65 is plenty warm enough, I only bring mine up to 60 and I`ve done bodywork in much colder conditions with no issues. Maybe try a bit more hardener next mix, at 65 degrees you should be able to sand it in less than a hour with no clumping the paper.
