I've started a new steamer project and have a hole to fill. What's a good brand of putty and what grit of sand paper is needed to smooth back down? Also, do I need to prime it afterwards before painting it the final color?

I use Squadron. The green should not shrink too bad. You'll want to let it dry about 24 hours before priming, def prime. Sand with 600 then 1200. How big of a hole?

Cut out a dome on a Mantua 2-6-2 plastic boiler. Also, can Squadron be found locally?

It should be found at hobby shops. Hobbytown should have it.

Thanks. Gonna put a piece of styrene under it to so my detail parts have a solid mount.

You'd have to to give it support.

I use Milliput. It can be formed easily like potter's clay. Has about 15 to 20 minutes working time.
No shrinkage. Can easily be wet sanded. I start with 320 and finish with 600 grit.
Strong when dried and I've never had it pop loose from plastic.
Unspoken expectations are premeditated failures.

| Milliput is nice too. It's an epoxy putty.

A tip on filling holes is to bevel the top side of the opening. If it's a drilled hole, carefully using a larger drill bit will do this. This method gives whatever kind of filler being used, more area of adhesion and less chance of a filler push thru.

| Do not use putty that has Tulene (spelling???) in it, as it will melt the plastic.
