get a glazing putty. Bondo brand makes two different kinds, professional and i guess regular. The difference is like a buck or two, so i just always get the professional. Anyway it will make it alot easier to fix that small holes. Also a high build primer will help too. It will fill in the small dips and pin holes. Walmart carries what they consider to be high build primer in the automotive section. It doesn't work as good as a professional stuff, but it will make a difference. Also what are you using to spread your bondo? What will help alot is to buy some flexible putty knives for body work. They conform better to the curves of the box and help get the bondo where its needed most.

you don't want to use a brush, use a hard card to "float" the material over the holes.

Did you go straight from fiberglass to bondo/resin mix? I would do fiberglass, then a layer of straight bondo, to fill the big dips, then bondo/resin mix, then when that drys i fill the pin holes and dips with finishing putty.

try just using bondo the resin mixture will make it harder to sand down due the resin the regular bondo wil sand and come out smoother and on dips use the spot putty it works wonders

I have not failed. I've just found 10,000 ways that won't work.

i am kinda new to this type of work but i like the bondo/resin mix. (5 to 1 rate) it is true that you will have to sand a lil more but you have a better and smoother finish to start with if applied right. bondo wipers are a must. you can get them in all sizes at any auto store.( autozone advance and so on) and thay can be cut to any size for smaller jobs. it is easier to me to brush it on then use the wipers to smooth it out somwhat. make sure to smooth it before it starts to set. also if you have large build up of bondo that needs to be took down try sanding it with say a 50 grit paper before it completly drys. 3/4 dry works best. it will gum up pritty quick so over the paper type i prefure the wire type like used on drywall. this way when it gums up you can just blow it off with compressed air. like i say i am still kinda new to this kinda work but i hope this can help you out.

The best investment I ever made a Portercable orbital buffer/sander, put the sanding heads on I used 220 I believe, wait until the bondo is completely dry, maybe a couple days, then the sander will cut through everything super fast and won't gum up, I tried to sand my enclosure a few times and my arm just about fell off. I got really frustrated and almost gave up on my enclosure because I couldn't get it smooth, I love my buffer, just have to watch out because it will cut down too far if your not careful and take out your layers of fiber glass. Just my 2 cents. Have fun sanding
