Google it.
I fixed several cracks in my motorglider canopy with it. Not invisible, but acceptable.
I bought mine from Knauff and Grove in Pennsylvania. About $50.00 a tube, but worth the money.
Carefully grind out v grooves on one side and fill with acrifix on one side.
Then grind the vee groove on the other side slightly into the glued (and cured) side to help eliminate the crack line.
After cure (in direct sunlight) I scraped the slightly raised plastic glue line with a single edge razor and then sand with increasing number grit until ready to polish out with fine compound.
Google other guys processes as well to make up yout mind how to proceed.
