Floor
 
Hi, I am new to the forum and had a couple questions regarding a t-bucket project I am currently constructing. My first question is what kind of fiberglass resin should be used to fiberglass the wood floor to the body. The body is made out of polyester resin. My second question is should I use mat or cloth.

Thanks
Tyler

Tyler, I am thinking regular old polyester resin and cloth for the strength. But there is a thread in the lounge called "Getting rid of the ugly" by "NEW INTERIORS" (Randy) and he did that very thing on a bucket in that thread. He did an outstanding job on it and you can see most of the stuff he did there but if you don't get your answers just ask him in the thread.

I posted this on your other thread..


I use polyester resin without the wax in it.... If it has the wax you will have to sand it everytime you glass something else... Without the wax you don't have to sand between glassing..

I use the chopped mat.. And remember this one rule... If you don't want a line to show when your done glassing,, Don't cut it with a scissor,, Tear it, That way when your done glassing everything will look better... I hate it when I see guy's glassing things in a car and you can see the lines on EVERYTHING they glassed in.. It might be covered with Interior.. But I know it's there..Do it right, Or don't do it at all..Good luck.

You reminded me Randy, I haven't done that in years and one has wax! As I remember it was called "B" coat, with the first one you would use without wax is called "A" coat, is that right?

The tearing the mat, GREAT idea! Yep, never did it that, LOL, I can picture a particular job right now on a 65 Vette hood where you could see the repair when it got warm. DAMN, great to learn this stuff years after doing it wrong. :rolleyes:

Never knew it as B or A.. that's new to me.... The one that has no wax will stay sticky until it get's enough dust on it... But it's good when you are doing a lot of glassing... The one with wax is good if your going to be done after you galss....

I seen a brand new 41 Willy my friend bought and the tubs and floor was glassed in after the body was built.. Man talk about a mess.. And this was a big name car... I know it really doesn't matter because you will never see it... But it had lines and drip's all over this thing...No reason for that kind of job..:mad:

When you tear the mat and glass it in.. If done right you can not see the repair.. That's how it should be done... Here's a picture of what I'm talking about.. Look for the lines in these two pictures.. Both had the floor glassed in after the body was mad.. By the way, This is the same body in both pictures..

Tell me which one you would feel safer gone down the road in..;)

Yeah, what you did looks like it belongs there, like it was made with the body. :thumbup: The way the floor was done before looks like an after thought and not very strong.

Brian

It will still be as strong,, In some case's, But it look's like ******* !!!!
When someone does it this way. It just doesn't look very professional...
Think of someone patching a boat like this for someone...:pain:

So, the top picture is what happens when you cut the matting instead of tearing it. what is a good amount of layers of fiberglass to use? Are the steps , 1. lay down the resin, 2. apply 2 layers of matting on top of the resin, 3. apply more resin on top of the matting. does this sound right?

Resin isn't strong by it's self.... I wet out the spot I want to work,, Then lay the chopped mat over that spot, I then use my roller to make sure that first layer is wet out without any air bubble's,, Then start the next one right over the last,, The key to making a part strong is, To use as little resin as you can to wet it all out,, A lot of resin on top of the mat doesn't make a strong part,, It only makes the resin brittle..

If I'm building a scoop or something like it... I will go with three layers,, three layers when dry will not give much... If I'm making panels to make some turns in it.. And I want the part where I can bend it into shape,, I will lay out one layer,, Once I bend it into the shape I wanted it.. Then I would lay up two more layers.. Then it will be strong and in the shape I wanted it...

When I glassed in the floor of this bucket... I grind everything with 36 grit, Wipe it with acetone,, Then I start laying the glass.. If your doing a hole repair,, Start with one size of chopped mat, Then when you put the next one over that last one, Make it a little bigger then the last and so on.. That way you don't have a build up in one spot..

If you stop for the day and come back tomorrow to finish what you started (you can do that with fiber glass) Pass some 36 grit over the spot, Wipe it with acetone, It will get sticky again, Lay up more glass,,;)

MARTINSR 01-16-2013 10:12 AM

Great stuff! I am blown away at that tearing the mat, I can't believe how I missed that all these years, guess that is what I get for learning stuff on my own and not having someone showing me. I have done a fair share of fiberglass repair, even making parts from scratch, never did that! LOL That one trick was worth coming to this site this month. :D

Good stuff Randy, very good stuff.

The sky is the limit with fiber glass... It's unbelieveable what you can do with this stuff... I learnt from my good friend speedydeedy when we was building my Chevy LUV truck.. I had pro streeted the truck with a reg bed and ended up getting a step side bed for it... Well the bed didn't fit over the tires... So he said let me cut the lip off the back fenders and widen them 1''...:nono::nono::nono::nono:

I knew he was one of the best with glass, But I didn't even know how to mix it... I knew how hard it was to find another step side if he messed it up.... So I said we have to go for it...

Well I was watching every move he made...:eek: And was blown away at just how easy he made it look.... I kept telling myself... Now this would be something for me to learn....Well we finished the truck.. And I was off to learn...Believe it or not... This is the very first thing I went home and built right after watching my friend...

And ever since then, I have been pushing the limits on what can be built with it... If I wouldn't have started the c-cab build.... I would be building bubble top one off hotrods... And that day will come soon.. Big Daddy will be Proud of me...Wait until you see what's next after the c-cab..

Here my first try at fiber glassing..:thumbup:
This car was built from a gallon jug..;)

I only posted this car to show it doesn't take a degree in fiber glass to build something once you learn a little about this stuff..;)

MARTINSR 01-16-2013 07:29 PM

It is wild what you can do with it. I am certainly no lover of it being it is an ichy way to get something made. :pain: But damn it's interesting. And I love the carbon fiber look on the right car.
