3M Dynatron, 358, 1 Pack of 3 Spreaders, 4”, 5” and 6”, Used for Spreading of Fillers, Caulks, Glazes and Putties

Q: Is this different than the 357 bondo spreader? they're both made by 3m and appear to be the same size...is one more flexible or any other difference?

This is a simple piece of hard plastic. Not flexible.

Q: Is the back completely flat?

Yes, there is NO raised text on the backside. There is the hole that you can see in the picture. However mine are/came warped - curved longway. Good luck with your project!

Q: Hello can I use this to fix Partial board kitchen cabinets? Thanks so much

Not fully understanding the question, if you can use the spreader to fix a cabinet, the spreader will add no value to strength or structure to a cabinet. The spreader is used to spread body filler and glazes on surfaces.

Q: Can you use this for touching up shower grout?

These are flat on the bottom but grout typically is "indented" a bit. It would be easier to use your (wet) finger or the bottom of a spoon to press in the grout.
