should I dip the cloth into the resin or should I put down the cloth on the fairing and then brush the resin on top?

 

Cut the cloth up into the desired sizes and according to how many layers you want to use, before you start to lay it. You're going to have to work quick, so get everything ready beforehand. Mix the hardener and resin, then use a short brush to apply a generous amount (medium heavy) on the repair area. With your latex/nitrile gloves on, place a single layer of fiberglass on. Brush on more resin, while simultaneously working it into the fiberglass weave and getting out all the air pockets. You will see this because the fiberglass will change from white to a translucent. Getting out all the air is important for achieving the best results.
So that's the basic sequence to laying it down. Apply resin, lay down the fiber, apply more resin and work it in; repeat until the desired thickness is obtained. The brush should have short bristles, about 1", so you can use it to force the air out.

 

How many layers do you recommend I use?

 

I'd say at minimum 3. But for example on mine, I wanted to reinforce the fairing so it wouldn't bend at all, which is what caused the cracks in the first place, so I used about 5-7 layers, which is pretty darn solid.
What I would do If I were you, is practice a little bit with it to see how it behaves, before you go on to the actual repair. I don't know if you bought the supplies yet, but Home Depot sells everything you'll need for around $30, and it should be more than enough.

 

^^^ Is it a kit that Home Depot sells or I have to buy everything separate?

 

Separately, but the products are literally right next to each other.
