Brian -
I special ordered a 48" wide roll. Yes, there are seams. I wanted to keep the physical layout as original as possible. It would have been a WHOLE LOT easier if I didn't use seams though!
Pat - It took me aboiut 7 months working on it here and there. It was a very fun project! The only parts that don't bring it back to 100% original are the veneer and I also had all of the aluminium trim chrome plated. Usually I'm not about "flashy" chrome add-on's but on this project I thought it would look ok.
There re three main types of veneer on the market. PSA (Pressure Sensitve Adhesive) Backed, Heat Activated and Paper Backed (Glue-on).
I have never used PSA Veneer but will probably try that next. I've used the other two with great results. Using the paper backed means that you have to glue it with basically rubber cement and then roll it and weigh it down to get it where you want it, fairly challenging for the first timer. It's all about proper placement on the first try. Once two peices of material coated with tacky cement on them meet they don't move a whoile lot afterwards!
