paint and bondo

Recon

i need some paint and bondo for laptop mod im doing.
so im just wondering what types of paint and bondo would you recommend that wouldnt eat the plastic

Justan

umm, maybe a bondo that has some fiberglass in it. ( not sure ) but if yuo go to a home depot or canadian tire, they will help you.

fiendofmine

bondo? whats that?

keybenusa@aol.c

its like glue that connects things

lydaan

its actually a fiberglass filler thats usually used for car repairs. when you get a dent that cant be pounded out, you fill it with bondo, and paint it, and it makes it look like there's no dent.

I believe that bondo wouldn't eat plastic at all, but do what Justan said just to make sure...

I don't think it would eat plastic, I've seen xrdotimcr use bondo a few times on his projects. It just needs to dry and needs sanding down once finished.

I am using Bondo on the front of my new case right now.

It most certainly does not eat plastic.

I've used bondo a few times now, its pretty much safe on anything, and toothpaste gets it offa your hands incase you need to..

keybenusa@aol.c

thats a good idea to use it on cases maybe i will get some for my case door

Recon

You've all been great help, but none of you have adressed the paint will duplicolor, NAPA, or Dupont eat the plastic.


To explain my newbie question: I used to work with paints all the time, but i stoped for a while because of extenuating circumstances. I know that some paint companies will change the chemical make up of their paint, whether it be to cut cost, or make it more efficent. Some times this change will make the paint volitile to plastics.

What i am asking is anyone who has reicently used any of the paints above or any high quality spray paints to tell me how it interacted with plastic.


Thank you for your comments.

I personally dont know much about what you listed, but Krylon from the local auto store is widely accepted as pretty much the best paint for your case, metal or plastic. i would guess at least 90% of the people who have painted around here have used krylon for it.

R.Carter

Recon, I don't think that any of those paints will have any volitile reaction to the case plastic.

If you are unsure, you can request a Material Safety Data Sheet on each of those paints from the store that may supply them. While they are required by law to furnish these on request, you may have to call the manufacturer.

The MSDS will definately tell you if that particular substance will have any adverse effect with any other particular substance.

But again, I think that you will be ok.

Alright well since I had to rebondo the top, I figured I should take some pictures of the bondo process and explain it best I can.

First off the supplys needed.
Bondo.
Cream Hardeder (should come with bondo).
Tac Cloth.
Small Acrylic Sheet.
Puddy Knife.
Tool to Open a Paint can.
(all seen below)



First thing you wan't to do is remove any dust from the place you are filling. You do this by using a Tac Cloth. They are very cheep and can be found anywhere sanding supplys are sold. Once its clean set you victum on a level surface.
Now its time to mix up the bondo!
Take your tool/screw driver and open the bondo paint can. Yes its going to be a light gray color. At this time its OK to leave it open for a minute or two when getting your mixing sheet/acrylic sheet and puddy knife ready.



Once its opened, make a rough guess on how much you will need. Just remember try not to be short. Its better to have a little to much, then not enough. Scoop the desiered amount onto your mixing board (my acrylic sheet).



Once you have the right amount spread out take the cream hardener and squirt a small amount onto the gray bondo.



Now its time to mix it up, it should be a redish/pinkish. If it seems too gray then add a little more.Once this is mixed you only have about 2-4 minutes of spread time.



Spread disiered amount onto the needed area. Try to blend a little too, make as thick as you want.



Bondo takes only 30-45 minutes to dry if its 1/2 inch thick. So before you go sanding make sure you have waited at least 30 minutes. Then sand, like you normaly would.

Hope this was helpful, just remember be confadent, its easy!

Till next time.

Thats from my iBox work log.

Recon

thanks,

i plan to be taking pictures for my work log as well

illustrious

Looks like you have a nice workshop there GI Jesus.

So Recon are you going to post a worklog of it? I would love to see how/what you are doing!

my girlfriend wants me to paint the lid of her laptop, but there are deep scratches. The bondo would only be a couple of millimeters thick and would need to flex with the lid. Would it be tough enough for this?

Recon

you if there only small scraches then you should use some kind of finnishing butter. Bondo makes a glaze and that should work. the glaze can only go on in thin layers, but the bondo body repair kit can go up to 1/2 inch.

keybenusa@aol.c

i thought there was only one kind of bondo

Justan

umm no,,, my dads a mechanic, what you do for a dent, is you pull it out, or cut it out, then you put a new peice in and match it, then you weld it in, grind it, bondo it, sand it alot, then you primer and paint.

lydaan

Yes, this is correct, if you're a mechanic. People who dont want to spend the money for a mechanic to do that spend $20 for the bondo and paint, and do it themselves.
