Hey guys I seem to be struggling with preping my roof for the headliner. I have a all metal roof with just a couple metal roof bows. I plan on cutting four more from wood to attach to, I have a pattern made but have struggled to get them cut out right. I tried a jigsaw and they sucked so I am starting over with a band saw. I have dyna matted the whole car and I tried using some 1/4 inch lathe and siliconing it to the roof, I'm not sure if there is enough strength in the silicon. I have no other choices in a couple spots but to adhere to the roof panel I'm concerned that if I use something to strong it will heat and cool at a different rate than the metal and distort, anyone else did something similar out there. Thanks for the help
