    I have an old Tillett fiberglass seat that has numerous old mounting holes. Looking to fill the holes low budget while I save for a better kart. Hope to make just a little more solid for my 195 pounds to not crack it

    Home Depot has a can of Bondo Glass for $14. Or should I go with their other option of Fiberglass Resin / hardener / cloth for @ $30? Or recommend something different?

    Thank you!

    I have used a product called Dyna-Hair which came recommended to me.  I picked it up from O’Reilly’s.  It’s pretty easy to use and I’ve been very happy with the results.

    I just go to the auto parts store and get the fiberglass cloth/resin kit for repairing boats & cars.  Always worked good for me.  Like any fiberglass job, getting all the extra resin out and the cloth nice and smooth before it hardens are key.

    I couldn’t find Dyna-Hair, but found a cloth kit for $17 at walmart in the auto section. Starting now and will post pics after. Thank you ALL for the advice!

    I wrote this article several years ago for a magazine and recently found it floating around on the web.  Written specifically with kart seats in mind,but also provides general info about composite construction techniques applicable to any industry.

    I get some fiberglass rod or even wooden dowel and cut disks to epoxy in the holes before patching over with cloth.
