I had a gunsmith tell me he's had very good results, anyone else?

Not the question you asked: I have good luck drilling holes with a small drill bit, and also using a coarse sanding sleeve to scuff the surface. I haven't tried the product you show. Never heard of it before.

That's the way I do it

Yes, the mechanical bond is SOP, just wanted to know if this might make it stronger.

I just use marinetex grey - and rough up the surface.

Marinetex is designed for adhesion to gelcoat, paint, fireglass, marine metals, and plasics .. (being funny) you know, like, boats and stuff

You might contact the company that makes it and ask if it's compatible with the material you want to use it on. If you do please post here what they say.

Scuff sanding, cleaning then promoting the bonding surface is the best of all worlds.

My question....

"Re: Bulldog® Adhesion Promoter, will this help adhere epoxies to injection molded plastics?"


Their reply...

"Yes. Bulldog will adhere to most plastics except polyethylene. Please see the attached Technical Data Sheet for your reference."

You ought to buy a can and try it. That size would be a 100 year supply for all of us!

Thank you sir.

How long does it take to set up??

I also use Marine Tex exclusively.. its the best IMO..For the beginner Id advise one use Brownells Jel until he gets the hang of it..follow directions very carefully.

Degrease thoroughly before anything else as there could still be mold release agents on the plastic.

Drill a bunch of angled divots into the plastic.
Most epoxies have limited ability to chemically bond to the "tupperware" plastic stocks. You want to get a mechanical bond.

Take a carbide burr in your rotary tool and thoroughly rough up the surface- again, for mechanical bond to the rough surface.

When laying in the bedding epoxy, be sure to work it into all the divots you drilled.

Use a hair dryer to warm the glass up once its applied to the stock and before you set the gun into the mess, an it will allow the glass flow into those cut outs and cracks..It also makes it flow clean and avoids those evil voids, one should always avoid voids. (pun intended)
