Hi Peter
The official line out of 3M is that the US use a product called 181 series (same product but more aggressive adhesive) as a lot of US application for stainless included corrugations – This is not very common in Europe and therefore 3M have never used 181 series in the UK. If application is as you say flat or with only gentle curves the 180 should be absolutely fine. As long as certain rules are applied including using 3M Surface Prep to clean down and wipe off residue and secondary cleaning with IPA , apply at correct minimum temperature and use plenty of pressure (as 180 is a Controltac Adhesive) you should have no problems – 3M have never experienced any failures with 180 on stainless as long as these guidelines are adhered to.
If application is more tricky such as more complex curves or corrugation then IJ380 or IJ3650 would be suitable alternatives.
Hope this helps
Stuart
