Need Fiberglass repair help
I have 3 Motorhomes. All near Identical. 2 Have major Damage to the fiberglass. All three have serious cracking of the gelcoat. I have done a decent amount of autobody stuff on non professional level but have never worked with fiberglass. My questions are:
Should I make the repairs from the back of the panel or the front or both ?
Do I use Cloth or gorilla hair ?
Polyester resin or Epoxy ?
Also Is it work trying to redo the gelcoat or should I just shoot it with enamel ?
Every one of these motorhomes I have ever seen cracks like mine did. I plan on painting the green Travco in a Camo pattern. The white one with the blue stripe I want to paint back close to original.
How do I do the fiberglass repair ? Grind it out ?
I stripped some of the gelcoat off the parts travco to see what would happen. i comes off pretty easy with a high speed air grinder with a 6 in disk but has to be done carfeully so's not to gouge it. I tried using a DA with 80 grit but it took forever. The grinder was much quicker. I was told to skin the fiberglass with bondo and paint it. Is Gelcoat not worth it ?
They stopped using Lacquer ???? When ???
