Calculating coverage using an adhesive, sealant we have provided the following chart that will assist you in calculating coverage. Lab metal from Alvin Products is used to fill, seal and repair dents, rough welds and small holes on any metal surface

Seam Width in inches
		1/8	3/16	1/4	5/16	3/8
	1/8	96.3	64.2	48.1	38.5	32.1
Seam	3/16	64.2	42.8	32.1	25.7	21.4
Depth	1/4	48.1	32.1	24.1	19.3	16.0
in	5/16	38.5	25.7	19.3	15.4	12.8
Inches	3/8	32.1	21.4	16.0	12.8	10.7
	7/16	27.5	18.3	13.8	11.0	9.2

Given the Seam dimensions, this chart provides lineal feet per cartridge. This assumes no waste.
