In the worst case scenarion, would there be any comeback on the company that paints it?.
A mate of mine's a sprayer, I keep meaning to ask him about this.
If you want to ensure option of going back should it bubble or lift you must make it absolutely clear yours is a plastic tank, petrol fumes will permeate through the tank and you want them to use paint that will not react with the fumes. This is very different to paint splashing onto the surface when filling up, important you make sure the sprayer is clear on this.
Get this in writing in the form of a formal quote before you agree price and allow work to start.
There are certain polymers which react adversely with petrol and others which don't. Note there is a difference between permeability, ie petrol fumes will pass through but the inherent structure will not be affected (like the tank itself & what you want the paint to do) and chemical incompatibility where the petrol will react with the structure and the plastic will 'melt' or stress crack (craze) and fail.
The secret is to get a paint which is based on a non reactive polymer.
Tuned In. You're thinking of Plasticisers. These are additives to polymers (plastics) which allow a degree of flexibility, the more plasticisers the greater degree of flexibility.
Hmmm sorry 'bout that, rambled on a bit there.
Bottom line, if your going to a pro paint shop, get it in writing first and you should be covered.
Good luck.
