I am wondering what to use for the topcoat. I bought bondo body filler but I havent heard to much good things for laying on top of the fiberglass mold. Will it be good or should I go get something else? I seen gel coat, how good is that stuff?

I doubt Bondo will produce what you want. Stick with fiberglass fibers and resin. -

You've got the right idea. Tape off your seat really well, add foam if you want to make it raised or a different shape, etc, and then tape off the whole bit with green masking tape, overlapping by 1/2" or so on each pass. Cover the whole thing in a thick layer of car wax (easier to find than mold release stuff, and works perfectly) and then lay down the fiberglass. Lay it thick enough that you can take an 80 grit wheel to it afterwards to smooth it down, and then use body filler over top, and sand until you get it smooth.Any and all statements by Loudnlow7484 are merely his own opinions, and not necessarily the opinion of Katriders.com.

I don't know how you laid it, but my favorite way is to cover a table in plastic, and then cut dry chopped mat (not woven) to the correct size/shape to cover the whole thing. Use 3-4 layers of heavy mat, and then stack them on the table, and soak them with resin. After about 5-10 minutes it will be much easier to mold it to the shape you want, and you won't have to finger f*** it so much, creating all those little fly-aways. Don't mix the resin too hot, or after the 5-10 minutes your mat will be rock hard and burning hot!

Uh, yeah...... not enough catalyst (MEKP). If you buy resin from auto parts stores they usually give you just enough MEKP for the amount of resin. So if you use half the container of resin, empty half the tube of MEKP into it. Without enough MEKP, it will just stay liquid, or kind of jelly, but it will never harden.Originally posted by TjCase85 View PostAny and all statements by Loudnlow7484 are merely his own opinions, and not necessarily the opinion of Katriders.com.

if you use too much catalyst, it will stay kind of 'sticky' feeling....if you decide to give it another go, when I make them, i rough up the glass after it cures, then apply a light coat of Duraglass over it. Duraglass is a heavyweight filler that is super strong and actually has fiberglass hairs impregnated in it. I smooth that out, then use a lighter weight body filler (Icing from USC is the bomb) to finish it off before priming and the paint process.
I've made a ton of these things, feel free to pm me with any questions.Comment

This actual sounds like an interesting project. Would be cool to make a Buse tail so you have a single seat since most of the time I ride without a passenger! Most of the ones I see for sale seem to expensive to me.http://katriders.com/vb/showthread.php?t=110816

after you have a strong sturdy base you can use fiberglass reinforced bondo (kitty hair) for the top layer to smoothen out any inperfections but be sure to use a 60 grit paper to sand the resin before you add the bondo.
use a spot putty after the bondo.
Let it cure a few days in the sun before you prime it for paint. used a sandable filler primer.Last edited by hardlydangerous; 05-18-2010, 07:22 PM.98 GSX750F

bondo on top of fiberglass is not a good idea unless i missed something than you are planning on putting bondo on the fiber glass. it will flex and the bondo will crack and chip off. unless its another bondo product. the fiber glass reinforced bondo sounds a little stronger but not strong enough.
or i could be wrong i have never used fiberglass reinforced bondo so.....time to nut up or shut up
