Shaving

[apuforyou]

I'm shaving my antenna next weekend if weather permits. I have both Bondo and JB Weld, which would be better to fill in the hole?

[tunerman]

i'd go with bondo.

if you just do bondo or body filler its just going to crack, you need some support, i did mine and i welded a piece of metal first, or you can jb weld a quarter then apply a coat of body filler over that, make sure to grind to metal for good adhesion

Forgot to add that I have also have the adhesive Bondo mesh

[heylookitsdylan]

If you bondo the hole shut, your gonna end up with a chunk of bondo the size of a quarter and a big empty hole in a few months. bondo isnt very strong by its self. save money, do it right.

also, Bondo shouldnt be applied over 1/8'' thick. or else expanding and contracting problems will crack it all up.

I use a gillet mach 3 turbo

lol


I would weld sheet metal on the inside and then bondo it from the top

Don't bother unless you have the capability to weld a blank in the opening first, and use a body filler afterward to bring up the low spots. JB Weld should not be used for filling holes, and Bondo is a surface leveller not a hole patching compound.

i welded a Quarter in mine. its CuNi though so you need access to a TiG.

but if welding isnt an option use fiberglass mat under the hole then fill with tiger hair (Mar-Glas, or any fiber strand reinforced filler) then sand, one layer of bondo, sand, last layer of metal glaze, sand and feather then paint. viola!

I dont have a welder and sorry if I sound like an idiot, but can i just JB weld some sort of quarter or a sheet of tin under the hole and bondo over it? Will the bondo still crack? And also if I did do the quarter or metal under the hole how well does the bondo stick to it? I do have the bondo mesh, but I guess its not good enough for this job?

hey sorry to jump in here but what kind of Metal Glaze is good to seal off the bondo becuase im doing rust repaires and the rust is coming through some spots of the bondo agian thanks, sorry for the sorta :P

['93accordse]

dont use bondo. If you must do it without welding, use a piece of fiberglass and resin and stick it under the hole from inside the car. (cut a long piece of fiberglass, tape the ends down, apply the resin to the middle part, let it dry, hair dryer will help speed that up, then once dry peel tape from ends and cut with scissors or sand down to get the loose mat off) . Then from the outside of the car use Fiber Reinforced filler, NOT just straight body filler. This will help avoid cracking. Now, fiber stranded filler doesnt sand smooth without pinholes, so you'll need to sand smooth, spread a layer of regular filler, sand that smooth then spread a layer of Metal Glaze. I personally use this all the time:
