If you bought this from the maker, first thing I'd do is complain about it. I once bought a '68 Mustang fastback body from Mini Exotics that had hundreds of pinholes in the lower body. Filling and sanding them would open up new ones. I complained and they sent me a replacement no questions asked.

If that won't work, you can try filling with superglue or some kind of epoxy. Good luck, and I feel your pain. BTW, don't sand resin without a respirator or AT LEAST a good dust mask on. Resin sanding residue is supposedly VERY unhealthy.

thanks Richard , ill email the company .What primer should i use on resin?

I know a lot of guys use Superglue to fill pinholes on resin but you have to remember the resin is MUCH softer then the superglue. You  have a very good chance of sanding divots around the pile of superglue if you are not careful. I would suggest using a 2 part polyester putty to do any body work on resin. it sands just like the resin so you aren't going to create more problems then you fix with it.

It is available in Auto Parts stores and sometimes in Wal-Mart.  Another option is to use spot glazing putty, which is also available in these two locations.

I would use a filler primer instead of any type of filler.

Spot glazing putty works fine for shallow pinholes, notice I said shallow... Just be careful to not apply it too thick. It does have a high shrink rate and will continue to shrink for a long time as it cures. That is why I recommend the 2 part for holes and such. Some of the pinholes can be pretty deep. The 2 part does not shrink so there is no danger of "sink marks" in a finished paint job after using it.

Uh, IF you do that sanding wet,  there will be NO dust--just sanding "mud"that you can rinse down the drain with water, my friend!  (Been doing it for decades now!)

I'm getting ready to fill some holes along the edge of a resin hood.

I'm gonna try this stuff:

 

The box says it is good on plastic and resin. Has anybody here used this stuff?

Is there a difference between 2-part polyester putty, and 2-part epoxy putty?  I used the epoxy stuff and it dried hard as a rock-un-sandable!
