Hello everyone! OP here. Seems like some people have picked up on this old post. For those who are interested, I did many hours of research after coming here and found out some great information; let me know if you have any questions.
With all intended respect, I didn’t find the previous responses, from very well intentioned posters adequate although definitely pointed me in the right direction.
I actually went through a local sign shop. They provided the best price and desired material. Despite previous comment, you can dictate which material to use as there are some major differences between certain material. Vinyl comes in several grades and you can definitely specify which grade. All grades used for commerical vehicles are NOT the same. I wouldn’t advise to trust the people who make these products to have it figured out. Just by asking several basic questions, I was able to verify who knew their stuff and who was selling a product that probably wasn’t what I was after. One that might work in the long run but I wanted to over research so I had exactly what I wanted and will be a permanent fixture on the canoe. I also wanted several unique designs so they were one off decals. This eliminated some of the online sticker sites.
In summary, research what grade vinyl you would like. Then compare prices. For me, the etsy and inexpensive sticker websites didn’t use the grade I desired. This is not to say that my conclusion is the best; only that it was what I wanted. I am sure that the sticker website’s products would do just fine, especially if you didn’t mind replacing them or leaving residual when removed. I paid around 70$ for four custom art decals that were about 7inch by 7 inch in size that are high grade, meant for curved surfaces and manufactured to last as long as the canoe.
Hope everyone is well! Happy paddling.
