  1. Hi. I have been doing truck hoods for 25 years and am trying to improve my skill set. We mold using gel coat but during a repair we use resin and Vette Panel Adhesive which is more or less body filler with extra resin. I understand the differences in the poly resins but why do marine repairers use gel coat for repairs? It seems to complicate things IMHO. Total quality repair yes but in our industry we'd get about 2.5 hours to have that in the paint booth and our jobs sit outside in the sun and go down the road vibrating every day. Great vid and thank you

  4. Can I use polyester resin on a fiberglass tub/shower?  Or will Bondo work just fine? Where can I buy the poly resin and hardener? Thanks.

  9. I have a really basic question. What happens to all those brushes? Is there any way to clean and re-use them, or does the resin just ruin a brush each time?

  12. I spoke to west system and they said that you could use polyester on top of epoxy, provided you let the epoxy cure for at least 18 days at 20 deg C.

  15. What's your opinion of MagicEzy filler for repair? I watched your video series about gelcoat color matching and have since ordered up all the materials to duplicate. Once I have a batch of gelcoat made up, I would like to then thin it out and use it similar to what MagicEzy advertises. Do you have any recommendations how I should go about doing so? I have a fair amount of superficial hairline cracks in my gelcoat and I'm uncomfortable grinding them all down to repair.

  29. would this be the same process I would use for the bottom of my old hudson trillium? Over the years it's it's accumulated many many stress cracks, and some nice gouges from being beached.

    We have already started restoration inside, this winter we would like to do the bottom.

  34. From the looks of this, you pretty much took off the gelcoat and a layer or so of the cracked glass. The problem is that the area is a flex point which caused the cracks in the first place. When we fix areas like this, we grind it down until we get to solid glass, not leaving any voids that would need to be filled with gel paste. Then layer it in glass starting with a biaxial glass for strength followed my 1.5 oz CS mat for buildup. Not knocking your work, but I would think that repair would crack again with any use of the boat.
