I'm on a few FB groups too, its another good source of information. But, I feel on FB there are a lot of armchair experts who can quite easily offend. When we finished our truck last summer some photos of it were posted on FB, not by us but it was nice to get he exposure.
Trouble is, then we started getting comments about how we'd done this wrong, painted it the wrong colour, something didn't look right etc etc
At the time it really got under my skin, after all our hard work to be sort of ripped apart, quite cynically tbh.
Whereas on the Forum, people have followed my restoration blog, really helped me at times where I've had decisions to make, made good comments and gave good advice that has really helped. I've also closely followed other restorations which have given great insights into things I didn't really see before.
I think that's the difference.
