how to get a dent out of your bodywork?
Metal expands and contracts at a rate of 2 to 1 to fiberglassHowever, Maple and/or Hickory does so at almost a 1-1 ratioIn other words, you would be better off using a hard, or semi-hard wood to complete your mission Since most expandable foams are rigid, and ex-con at a rate higher than the previous products mentioned, you are better off with metal lastHickory second, and Maple firstEven a Pine would be preferable.
There are several methods out there, but if you follow the link below, there are three quick, inexpensive ways (with video instructions) providedBriefly, you can use dry ice, a blow dryer and an air duster, or aluminum foil, a lighter and an air dusterThese techniques are all based on the theory that rapid temperature change will fix the dent without damaging your paint Note that these methods are quite effective with small to medium size dents, particularly the foil and air-duster method.
I agree with Kevinany kind of metal mesh frame would be ideal!
No! You start telling us you want to fiberglass and then digressDuct tape is always a temporary fixWall paper glue/paste is water solubleVisit your library and read about kayaks and how to build them.
wood should work just fineI've done it hundreds of timesThe amount it expands is minimalCardboard works great tooif you need to sculpt something with foam, put wax paper over itWhat you may need is a high density foam Don't know what it's called (the yellow foam mentioned previously)Like the same foam that comes out of the cans of spray expandable foam for insulationsorry don't know the name of it.
