At the current price for a cylinder of propane, it might be cheaper to buy a new chair? Especially, if there is a chance that the chair will fade again in a short time, as some have commented, then, why waste the time?
I think its normal butane torch. Idk its like $5 for a can of butane that will last 4 or 5 refills. Or just dont buy plastic furniture because it looks bad
It more just something yo do in spare time I'm sure ut was just to keep busy doing something. But it is good to know if the plastic black bumper of your car fades it may work never tried but I would if needed
Put hydrogen peroxide on it and put it in the sun removes degraded plastic, then hot torch it will last longer. Gas torching is great for fixing plastic console chips and scratches.
