so i took my wing off, taped off the holes and sanded to bare metal, i have one coat of bondo on it been an hour sanded down it is still a tiny bit soft is this right im ready to but another layer on am i doing this right?

 

you really should have welded the holes shut. with out any re-enforcment on the back side the bondo may crack. get some glazing puddy or finishing bondo for your last layer. no pinholes in that stuff.

 

i dont have pf that stuff on me at the moment im just trying to gt it as good as i can here at my shop, then the [aint shop is finishing it im just dping what i can to save a few bucks smy other tips on what im doing would help alot thanks

 

you didnt add enough hardner thats for sure......but then again you might of. what your weather conditions like? above 70? bondo doesnt like to dry at lower temps or very high humidity. takes longer

i know when im doing my body work i start on one car and when i get bondo on it i go to the next car while it cures. you could try to add a little harnder. the bondo should be a lighter(not too light) shade of blue or red depending on the color hardner your using.

also you dont want to apply a new coat of bondo over wet bondo this will cause a metric ass ton of pinholes when it finally cures.

my best advice when adding hardner to bondo is put your blob of bondo on your bondo board or whatever your using, take the hardner tube and start from the middle and run a bead of harder out to the edge. thats all you need. over hardning can cause pin holes, and crap work time.

 

or atleast fiber glassed them....if he had a highrise im pretty sure the trunks dented from being used...thats usually the case. evercoats metal glaze is my favorite final coat glaze to use. its awesome.

 

take that bondo off, get the holes welded shut, grind it down smooth with a grinder or 80 grit on a d/a. then throw bondo over it sand down smooth and feather the area out. primer, sand with 320. dull down the surrounding area with sandfix or wetsand. get it painted sealer, base and clear. DONE

 

i waited an hour bwtween ;ayes i just about ot put sencond one on now....im inside a heat shop

 

i would get the holes filled or sand it down and glass them shut. you cant rely on bondo to keep them shut. its going to crack.

 

Get them filled... with u livein in canada it won't make it threw ur first winter.... it happend to my old truck last winter.... good luck....

 

would it not much cheaper and less headache to buy a yellow wingless trunk lid from a wrecker?

 

This right here. Clean the bondo out and pay someone $50 to weld the holes shut and grind them down smooth. Then primer, base and clear it.

 

At a minimum you should have used bondo with kitty hair. I've also done it where I've backed the other side of the holes with fiberglass mesh/epoxy, then attacked the holes in front with bondo. Without any support in those holes, the bondo will pop for certain.

I'm also one for laying down a layer of primer before any filler, since you can rust pretty bad behind the filler - especially with it exposed through with those holes on the inside of your filler treatment!
