i have the skeleton of what i want built and wrapped in fleece and added resin last night now tonight i did my first layer of fg matt now i know that i should do like 7 or 8 layers for strength but after all the glassing what do i use next, bondoglass? i want the finish product to look like the exterior of the car. Any help is mostly appreciated.... thanks

 

wow 8 views and no comments or help lol i guess im not the only one who doesnt know what goes on next lol

 

ok after you have built your skelliton cut your fibre glass mat into 3" by 6 to 10 " long pieces. apply them chris crossing them for strenght.
thats for the inside for the outside you are gonna want to mix fg resin and plastic bondo the white stuff mix them 50 50 and to harden them use the fg hardenerdo one coat maybe two then after you have sanded use a light layer of bondo oh ya for the inside if you want extra strenght use some kitty hair fibreglass bondoround out your insde corners and joints it helps i hope this will help.Dan

 

plastic bondo ? what is that? lol i was wondering after my layers and layers of fg what do i use on the outside of the box to get that paint like finish?

 

^ I generally suggest that people avoid putting fibreglass mat on the outside of the enclosure at all costs. It makes it WAY harder to level out for painting. Build the thickness from the backside.

Sounds like it may be a little late for that though...

What you want to do is sand the fibreglass to as smooth and perfect as you can. Once you are at that point, then you use as little body filler as possible to fill in those last pinholes, air bubbles, etc so it is completely smooth.

If done correctly, you should use almost no filler.

 

lol seriously got any pics or videos of what your talking about?

 

This site explains it alot what to do. Very simple and i used it works great.

Fiberglass and Interiors : How to Make a Fiberglass Enclosure

 

^ Ok, that thread shows exactly what I said not to do but it's useable..

See how they piled the fiberglass on the outside of the enclosure? That is dumb. Take the effort to apply the fiberglass on the INSIDE of the fleece. Done properly, after stretching and soaking, the fleece is the shape you want and pretty darn smooth. A little time with a sander and you are ready for primer. Why botch that up by glopping fiberglass on the outside? Sounds like more work to me...

Anyways.. See the step where they then sanded the fiberglass before icing it up in bondo like a cake? Now they state that this is just a light sanding to get rid of bad surface nasties. The smart route at this point is to keep on sanding that fiberglass until is it smooth and 90% perfect. THEN you put on minimal filler to get that last 10%. By slogging all that bondo on there so early you have two problems: First, you are now a sculptor trying to get your shapes straight and levelled back out which will result in thick areas of bondo and thin areas of bondo. Generally this is bad and usually results in wavy panels no matter how much you sand. Second, bondo is not strong, and it does not like to flex. Work like that is a crack-o-rama in the waiting...

I'll try to take a pic of the 'glass baffle I made for my car that I wound up not using. I was able to get it to that 90% with no bondo.

 

ok thanks dukk
