Been biulding my current speedster body this weekend and usually give it a coat of fiberglass resin.
Just wondering what others use to seal the wood grain before painting

I've used West System Epoxy. I thin it out slightly to get maximum penetration and then sand it lightly so the paint will adhere. I do this only where the wood is in contact of the metal. The exposed wood I use Rustbullet automotive gray. This is just how I do it...

Thanks Don I know what I've done, but trying to see
What other have done.
I've used west epoxy on a wood boat

Bob, I use Kwik Poly. Langs (and others) sell it. It is a 2 part product. It has the consistency of gasoline or water when mixed. So it soaks very deep into the wood. It is also great to treat soft/rotten wood as it hardens the wood into a hard and stable wood again. You can make molds from silicone and cast small parts like dash knobs, gearshift knobs, ect with it. It sets up very fast. You have about two minutes to work with it in the summer and maybe 4 minutes in the cool weather. So you need to be a little "sloppy" with it. It sands good and takes any kind of paint well. I have used it for years and love it ... I can not see getting by without it after I tried it... But that is just my personal opinion on it. ....

Donnie been using it for years repaired alot of t
And wood wagons
Gas tank sealer
Tightening of wood wheels and top bows

I would use a good exterior oil based penetrating wood primer such as is used on the exterior of a house to protect it from the elements. 25 years ago, I primed my house with just such a primer and painted it and it has held up very well. Wood is very tricky because it expands and contracts with the weather, I would be leery of using a fiberglass resin or an epoxy on the bare wood that does not move with the wood. Chances are it would crack and expose the wood under the cracks to the elements in a very short time. Jim Patrick
