Fiberglass & Putty Questions:

[Captain D]

Hi all,

I was talking w/ someone in a local shop and we were discussing bondo in general. Instead of using bondo, he recommended:

1.) Tiger Hair Fiberglass, made by Evercoat, for filling small holes instead of Bondo's brand of fiberglass,
2.) Dynatron's Glazing & Spot Putty (roughly $40 per tube) for filling in small scratches & blemishes instead of using regular bondo.

Has anyone ever used these products before and if so, what are your opinions/experiences? He also said that the Tiger Hair mixes with the bondo hardener and can be applied easily with a putty knife.

Thank you for your responses,
Aaron

Simply, the other products mentioned are a better quality than "Bondo" brand body filler.

Not sure if I'd be filling "small holes" in a structural part such as a frame rail, your better be cutting that garbage out & welding in new metal!! 


Just a side note, but my personal favorite body filler? Rage Gold.
Glazing putty? Evercoat Polyester Filler. Dynatron's isn't bad, either.
I've used Fiberglass fillers sparingly, best place is over welded panels such as the roof C-pillar or lower rockers at the quarter panels.

If I got a big rough or low area or over welds I use the Fiberglass filler instead of bondo. After the fiberglass then a thin layer of bondo (body filler) & then after that a thin layer of glazing putty (evercoat) to get any minor pin holes ect, ect left behinfd in bondo. LEON.

I heard metal to metal can be very britle, i havent used it but for some issues on my car its worth a try.  Is it anything like jb weld?   

[SFRT]

no...you mix it with hardener and it goes on really smooth. it seems to have little metallic bits in it. I am using it for small cleaned out rust pits and it seems to feather in really nice. it sets up really quick. I am finding it easy to use. then again, im an amateur. on a couple of 'larger' holes I grafted in new sheetmetal, used a backing plate and welded the repairs.

I have a weird thing against 'bondo'...I am sure this stuff is probably just like bondo, but it seems nicer!

Personally I prefer anything by Evercoat

Thank you for the many responses - it sounds like these 2 items are worth using and recommended over the Bondo brands. I would like to snap some pictures and post for y'all to see, but instead of fighting w/ this computer, I'll describe as best as I can the areas I thought about using the Tiger Hair Fiberglass.

To be upfront - none of the fiberglass will be used on structural areas. No frame rails, nothing mechanical, ect. The only areas that I was looking to use it was:

1.) The very bottom area of the rear back window. At the very base, on the inner area of the sail panels, there is a hole about an inch & a half in width on the driver's side. The same small spot for the other side as well.
2.) About an inch and a quarter spot on the rear tail-panel area.

In these areas, it's a little tight to crawl up inside the trunk and lay down & try to weld a small piece of sheet metal up to fit these areas. So, that's why I'd like to use the strongest fiberglass money can buy. But, if you guys think that there should be metal behind those areas, I'll see what I can do to help make it as strong and *durable* as possible... So, no hole is very large, at max: an inch and a half.

Thank you again for your time & suggestions!

weld in patches ......none of the fiberglass products should be used to fill a hole.

[mikepmcs]

I agree, find a way to get new metal in there.

Okay, that's what I needed to know...I'll see what I can do! "Thank you" again for the info! 

Kindest Regards,
