Lots of bondo.....well there is a reason.

Post by megaglow_z on May 16th 2008, 1:22 am

OK, The bed on the yota is trash, But it will be a while till i can find a decent one.
I will probably have to live with this bed, as they are hard to find not rusted.
I have beat the thing into reasonable condition, and got creative with the bad corner...lol

I have a metal skull mould that i will be attaching to the spot...
This one.


here......




I will need to mould around the skull form and make it look like its pushing out of the bed.
My questions are....

Is there enough difference in the premium bondo to make a difference?

Will upping/lowering the amount of activator change anything like hardness?

The bondo will be about 1 1/2 to 2 inches thick in a few places...how long should the cure time be between applications, or should i try to build it all up at once, then add small amounts to finish?

Should i fill the air pocket behind the mould with anything, and if so, what?

And do you think i should do both sides or just the one?

Its something that will not really be noticed at first, it will just be painted the same as the truck, no airbrushing, just a neat touch that people will have to be looking at the truck hard to see.

I think you will be better off using fiberglass using that mold. Bondo that thick will crack and start falling off. If you go to this link they have a fiberglass section that will help a lot.

What Roadking said but to answer your bondo question, the amount of hardener you use determines the speed the filler sets up, not the hardness. I have read that too much hardner may make it a bit brittle but I don't know that for a fact.
Thats a neat custom touch tho but I think I would put a few MINOR highlights on it. You know, kind of like they do to make ghost flames. They are almost invisable but in the right light they stand out. Of course they are usually done in pearl paint but you could get the same effect with some super thined white and a small brush or thinning the base color with white and doing the same thing. Anyway, I like it.

I should have explained better... I'm not making the skull out of bondo, I'm just filling in around it.
The skull will be tack welded to the truck, then fiberglass strips around it,then bondo to smooth.
My brother did one on the front of his van ALONG time ago. he cant remember exactly how he did it, but this is pretty close to the way he did.


And ill look into your highlight idea Smile

And should i do both sides????

Maybe if i build it up to almost level with fiberglass, then bondo?
Would that be better?

I went back and looked at your skull again and I think I would grind the raised edge off before I welded it on. This way you wouldn't have a big lip to fill over. You could just grind the weld smooth and only use a skim coat of filler. It would be like a patch panel.
You do know that bondo is only recommended to go on in 1/4 in layers don't you? (LOL) I have seen it up to 2" thick in one shot and it held. When it kicks (cures) it is all the way through.
I don't try to put it all on in one coat because a person tends to build it up to much. Put on the first coat and sand it down with a board file and then put on more. This way you can tell where your low spots are because they will show as not being sanded. You still have to sand them tho but I do it with a different pattern or grit paper so you can see them.

But i figure the bed is trash anyway, and if it messes up, ill just drive it bedless....lol

This thing will be over the smashed part. do i need to fill the void behind it with anything.

I wouldn't think so. Just as long as it is welded solid and no water can get in there and cause rust. By the way, where did you get the skull?
