higher grits = higher flex?

General Discussion

I’ve been sanding my clear boards no higher than 100 grit lately… and i started thinking that maybe this could affect the flex.

If there is less surface area (higher grit) for resin to adhere to, wouldnt the board flex easier? more resin would be “sticking” to itself…

now if i used a lower grit, this would in theory create more surface area for resin to grab hold of…

would this affect flex? i realized that even if it did, results would most likely be micro-noticeable, but everything affects something, correct?

Fluffy,

By going up to higher grits, I would have to think that you would get more flex due to the fact that your would probably tend to remove more glass by the higher sanding schedule (100, 150, etc). Making the glass thinner and more prone to flex.

Although like you said - micro noticeable. Whether or not you ate that last donut before going out probably plays a bigger card :slight_smile:

Best,

Just to be clear on this, you’re talking about sanding the foam before glassing, yes?

While initial flex might be less ( more due to a faintly thicker resin layer rather than more suface area to adhere to) , ultimate flex ( before permanent damage set in ) might be considerably better, due to better mechanical adhesion. You pays your money, you takes your chances

Man I love grits, they taste so good. Cheese grits with shrimp are the ones that make you the most flexible. Grits are actually the food known to produce the most flexibility to the human race. Not a desireable effect for the aging man. They seem to be pretty set in their ways. No flexibility in necessary situations and too much flexibility in others.
