Poly-Flex Flexible Polyester Glazing Putty for Spot Filling and Skim Coating - 30 Fl Oz

I bought this to have something to fill cracks on a Star Wars costuming 2-piece helmet that I was working on and it did a great job! A recommendation with this for other uses is to use smaller amounts mixed with the hardening paste, as the instructions mention. It hardens very quickly but is excellent to spread when it is still malleable. I worked up multiple layers and then used 120 grit to higher grit to ensure that it levels down to a smooth finish. Did that a few times to ensure that there were no rough spots and it turned out fantastic! I have attached a picture which shows the helmet I worked on after clear coating, you can see minimal spotting with the Polyflex.

good product

Great product, my bumper is tpo had to fire treat the spot after sanding with a little butane torch then apply filler. Sticks like original no cracking. Got broken on the trip and amazon refunded it. They need to protect the cap end when it's cold plastic will shatter. A simple piece of styrofoam on both ends would have prevented the package from being damaged and leaking filler and stinking up the mail room.

This tends to clog sandpaper easily. It does work and is very flexible.

Stuff is awesome.. I was about to throw away my urethane bumper on my c3 and decided to try this. I hit it with 40 grit then vgroved and layed glass in seam then vette panel adhesive then used this stuff to glaze oi ver everything including sharpening my fender lines with it. Amazing stuff. I hit my bumper hard and no cracks or seams. Time will tell. But very happy so far.

My old custom car is chopped and welded across the roof. I have redone the work 4-5 times using conventional body filler over the last 10 years as it always cracks when the unibody frame twists a bit. I will eventually add frame connectors but i just used this product and it flows really well and since it's still flexible after it cures i am hoping it doesn't crack again or nearly as much. Great product and i am ordering more!

This stuff is super flexible. Recommend on any application where flexibility is required.

This stuff sands great and is really easy to apply. If you're still using bondo brand filler stop now and use this stuff. I use this on the endura bumper on a trans am and filled all the cracks and imperfections easily.
