	Primer is to be applied liberally to all PVC/CPVC joints, pipes or fittings (by use of a brush) where they are going to be connected together. In many cases, a brush is supplied with the primer. Application of primer should be done immediately before the application of PVC ~~cement~~. Most PVC glue manufacturers recommend that the cleaner not be allowed to dry before gluing the joint. As always, the directions on the can provide the best advice on the process of [[solvent welding]].

	The unsightly stains caused by purple colored primer can be made to look less noticeable by covering the rest of the PVC pipe/fitting with primer also. Multiple coats may be necessary to achieve the desired shade. This dyeing method is especially resistant to scratching and was used in this .25 caliber piston valve cannon made by BillyBobJoe of the [[Spudtech]] forum.

	It should be noted that this rifle suffered a fracture in the rear female adapter, which was most likely caused by an overtightened SCH. 80 plug. The primer only penetrates the surface of the pipe/fitting and once it has had time to dry and dissipate, overall strength of the finished product should not be compromised.

	Both of these are manufactured by ~~many~~ various companies and can usually be found at your local hardware store. Purple primer is easier to see when applied, clear primer can often be hard to detect after in dries. However, purple primer often leads to messy and unsightly purple smears on and around the project you are working on, best prevented by a generous application of masking tape around the non-joint area prior to gluing. Both are equally effective at getting the job done; it is up to you to decide which to use.		Both of these are manufactured by various companies and can usually be found at your local hardware store.

	There are two basic "types" of building primer commonly used with potato cannons: clear and purple primer(s). The difference is simply that purple primer has a dye added to aid in the enforcement of building codes. This dye is essentially impossible to remove, as it soaks into the pipe fairly deeply.

The difference is simply that purple primer has a dye added to aid in the enforcement of building codes. This dye is essentially impossible to remove, as it soaks into the pipe fairly deeply. The dye will also stain skin, fabric, wood, concrete, just about everything except metal.
