mix about 20%fiberglass rein with bondo just use bondo harder.
. makes it flow like butter and sand like glass. give more time to work with ( longer cure time) and wont pop from fiberglass

I'll keep that in mind, thanks for the tip!

glassie, what about hardner proportions for the added resin..........

the bondo harder is M>E>K>P paste just mix as you would with bondo put it take hours to fulley cure. the working time is the same as bondo

MJ I done this trick a lot, it works great. A lot less air bubbles in the bondo. You only need to use the bondo hardner, do not need to add the resin catlyst. bondo-resin-hardner. Oh yea it really does spread like very smooth peanut butter.

So if I understand right, the bondo-resin-hardner instead of just bondo & hardner would be good for filling small patch areas before primer paint or painting?
For my husband and I this is the first time using this type of materials.

...this sounds like a really good tip...my question...more specifically is...if you use X amount of bondo with X amount of hardnener, and then add 20%additional of regular resin, do I need to increase the bondo hardner by 20% or?????????

...inquiring and inexperienced minds just wanna know...

This sounds like a great idea on the surface, pardon the pun.
Jack, I'm going to assume that you would use the appropriate amount of catalyst for the combined quantities of bondo and resin. One question though, how well does this mixture stay in place on a vertical surface?
With the increased curing time and the consistency of the combined mixture, it seems that it would have a tendency to sag.

Kevin, you bring up a good point...my reason for asking questions about this technique, are 1) it sounds good and 2) it's a new technique here and I would like to see it better explained by those with experience using it for all the inquiring minds out there....

Go ahead and give it a try. Then you can tell the rest of us how it works!

...I just might ...it made me wonder aobut mixing epoxy with hi-performance, 2-part wood filler(bondo for wood)...I think may be in need of a good fairing compound...one day...

I'll give it a go next week one day when I can get some time. I will keep you posted on it.

It's like making a good stew .just add the harder that look right ( the ball changes colors) . It will slump on vertical surface don't add as much resin are put a baggy over it and smooth out let set pull baggy off. martha24 yes will work as you said

Use as much as you normally do if it cold add more harder if hot add less it take a lot to sag had no sag on this fender buck
