I painted with soapy water and confirmed a puncture.
I did a puncture from a floor and a connection part of the tube. The pressure and temperature of the iron to heat-seal did not seem to be enough.
I think that you had to make it very exactly when you make it first. I reflect.
Is “TUCK TAPE” the thing of $ 7.99 in the online shop?
Should I stick this along a seam from the inside?
