I'll repeat myself...It's a cheap laminate and this is what happens when you use cheap materials.
I am perplexed by these kind of posts
"I used cheap and it's not working"
Here is a thought.
Why not separate yourself from everyone else.
Use the best materials available,charge for it,make more money and justify your prices because your signs are a better quality than the guy around the corner.
While in full agreement on using better materials, what ends up happening in many cases is the average customer is so risk averse and cost conscious that they reflexively choose the lower bid and embrace the assurances of the salesperson telling them that they only use the best materials whether they are true or not.
We just redid two jobs worth over $2,500 total that we bid on three years ago that were considered permanent signs that we'd have used IJ35 or 40 on that ended up going to our closest competitor who has the words "Low Cost" in their business name. They both started burning, peeling and fading at about year two. I never asked what the clients paid, but I assume it was "lower cost" than our bids. Those two customers essentially have now paid twice for signs in three years time that should have been done right the first time by a more honest vendor.
We also have another nearby competitor who was putting wraps on without lamination and doing other cost cutting measures for several years as the business was sinking. Its no great comfort knowing that we've now picked up multiple new clients from those actions, but we were always perplexed why we didn't win those bids to begin with.
