99 caravan, front bumper

Ok im having a few problems understanding,I've been rading alot and getting no where, was wondering if ya'll can clear it up.

Ok I have a 99' caravan, trying to do a front bumper.

What  i'm thinking im going to do is, Remove the bumper, Wrap it tightly with fleece, Spread some resin on it, grind it down, make my cuts,resin it some more, untill durable enough, then i grind some more, bondo it in, paint it ect. Also, How will i remove the bumper from the fleece, after healing?

Now what I don't understand is, when ya'll use this matting, How do you glass the matting to not have any waves/edges?

Difference between using resin/ gel coat?

In summary, try little samples of various materials and see what works best

Anything else?

Ganbatte ne!

have you changed the shape of the bumper any to where you would need to wrap it in fabric? or are you just making a copy of the stock bumper? If you have to wrap it, I would suggest grill clothe or spandex. It's much thinner so It wont soak up too much resin, and you still get your nice shell to lay mat on. Thats just my opinion. BellsRacer knows her stuff so take notes.

Also, from the way I'm reading your post, it sounds like your just wanting to lay down some fleece and go nuts with resin... fiberglass mat is what gives the build it's strength, not just the resin and some fabric. That's just the way I read the post so Im not trying to insult you or anything.

Good luck with the build! Post Pics!!!

What I would do then is tape up the entire bumper and cover it in the "mold release" (I have heard of people using turtle wax as well) like Bellsracer said. After that it's time to start laying mat. If you're just making a copy of the original, you don't need any fabric of any kind, just start laying mat down (I would look into some 1.5 oz chop mat.) I would highly suggest investing in a roller since it's such a large area. This will help with keeping bubbles at a minimum and will allow your resin to go farther. You want the mold to be as strong and stiff as possible so when you do to layup of the new bumber it doesn't warp or anything.

have a good one!
