The original post was a comment about the paint used at Delta Force.
As part of my job, I go to suppliers premises and test paint for Delta Force. This is usually a full day per week, testing anything up to 30 batches of paint. We have a manager in the north who does the same up there.
We use about 20 pallets of paint per week and we use 3, or sometimes 4, main UK suppliers, the same guys who sponsor UK tourney teams month in month out.
When we select our paint it's not a case of 'take it it's cheap'. We test for how bouncy / how fragile it is, we measure the size and shape of the paint (pole/seam measurements/ dmples etc) take the temperature of the paint, and in winter we allow the paint to cool before testing so it's at the temperature it will be when it's used (within reason). When possible we test fire the paint as well, although some suppliers have an issue with mess and noise at their premises.
If a batch is too 'hard' (ie bouncy) we reject it. Same with all the other factors. I have often selected higher priced paint because the cheaper paint is not up to standard.
Paint is rarely stored for more than a week at any DF centre as we have such a high paint turnover. We have heated paint stores at our centres to keep the paint warm in winter. Keeping it cool in summer is more of a problem but the paint stores are insulated and have fans to circulate the air.
Transportation between supplier and sites can be a problem as most companies use pallet services to deliver, whose lorries are not temperature controlled. They load up on a Wednesday afternoon and deliver to the centres on a Thursday. This means it sits up to 24 hours in the cold, after just coming out of a 20 degree heated warehouse, then it's back in the warm at the centre. This is not good for paint and can cause it to dimple.
Incidentally, by the box prices at DF are £5 per 100 not £6 per 100.
