Glenn83 19 Report post Posted January 12, 2015 I have repro boss 429 hood scoop from MTF, I am going to try and get it moulded/bonded to my hood professionally if I can find some one to do it, a lot of people seem to think I am asking for trouble when mounting fibreglass to metal, has anyone got any thoughts or suggestions on this??

jholmes217 65 Report post Posted January 12, 2015 I know I've had two hood scoops bondo'd to hoods in the 1980's. One was a 66 coupe with a Harwood snorkel scoop (wish they still made those!) and a 67 with a 65-66 Shelby style scoop. The bondo cracked on both within a year.

shaun071 62 Report post Posted January 12, 2015 A mate from work (I work on helicopters) who is our fibreglass/composites guy suggested using Hysol 9309. It allows some flexibility between the steel and fibreglass to prevent cracking. Quote Share this post Link to post Share on other sites
