I install vinyl tops here in my shop and I can tell you if you have never done it before you will probably ruin your first top. It takes trial and error to learn when to stop pulling, when to apply more glue, how long to let the glue setup, when to use the heat gun, etc. Keeping it perfectly centered and the seams straight is a real challenge too. You also need to use a dedicated professional quality glue sprayed from a gun. I also have used rattle cans long ago and it is very hard to get the even coverage that is very important. Just my opinion.
