I found the G floor to be very slippery below freezing temperatures and when that included snow and ice I got rid of them before injury occurred.
That said, I don't have any real experience in summer conditions.
I converted a big box steel door by removing the brick mold and threshold and reversing them.
I tested the hinge pins but was unable to remove them with a hammer and a drift.
There is a step up into this garage so snow buildup is not an issue.
In all it makes more sense to order a reverse door...
I fixed a buddy's dryer last year. While there he showed me this bench that he didn't want to move when he sold the house.
My son and I picked it up on sunday.:)
I disassembled a door like that last year in order to recycle the aluminum parts as I tore down the garage.
Removing the panels from their frames would be impossible without destruction, and adding any weight to that light door, other than paint, would likely overload the flimsy hardware.
Paint...
I've been looking at that lift as well.
It suits me because of it size, it's included features, it is 110v and requires no air.
As I understand, it cannot be certified (ALI?) because of the manual safety latch, which does not bother me.
I got the G Floor mats on sale at Menards for about 150.00.
I put them on the slab outside and found that they were slippery when wet and treacherous with anything frozen on them. I had to remove them until spring.
Inside, or in a heated garage they should be fine as long as puddles don't freeze...
When I was a kid my buddy's folks had one of the first tv's with a wireless remote
It worked on sound waves, like a tuning fork.
When the dog would walk in and scratch at his chain collar the tv would go nuts.
My buddy would then beat the dog.
I'm sure this is of no use to you but, don't look...
