QUESTION: How do you know what lbs dent puller you will need?  I have dented creased (1 line 7") fender.  What material is the 1994 camry made of?

Would it be possible to cut the portion of the damage and put some sheet metal (or type of material that it is) and weld?

also on the doors for the weld, Cutting and Welding w/ respect and preacuctions / and/or removal of rebarrs of course!

If alls possible what type of welder should you use, tip type, flame setting for cutting setting and then for joining setting?  OXY ACECETLYN, OXY GAS/ MIG, OR TIG?

Is there a welder for fiberglass?


Thanks in advance,

Answer
ECONOMICAL DENT PULLERS ARE THE ONES THAT HAVE A SCREW ATTACHED TO THE END OF A BAR.
DRILL HOLE ...INSERT SCREW BY TWISTED IN SO THAT IT HOLDS ....PULL THE SLIDE DOWN THE BAR..
THE SLIDE WEIGHT WILL HELP IN PULLING THE DENT OUT.

FINISH OFF HOLES WITH BODY FILLER......DONE.

WELDING A PATCH PANEL AFTER CUTTING AWAY THE DAMAGE WOULD NOT BE RECOMMENDED.

YOU WOULD USE A MIG WELDER FOR ANY WELDING.

THERE IS NO WELDER FOR FIBERGLASS

IF YOU DO WELD ON A DOOR ...MAKE SURE TRIM PANEL IS REMOVED AND YOU KEEP A SPRAY BOTTLE FULL OF WATER IN CASE YOU START A FIRE.
