FILMAR made its debut in 1989 fielding a No. 8 Oldsmobile in the NASCAR Busch Series with Bobby Hamilton, who scored a victory at Richmond in September. The team initially ran without a sponsor before TIC Financial Industries came aboard in mid-1990. Hamilton recorded seven top-five finishes and finished eleventh in points that season before departing for the Winston Cup Series.
David Green replaced Hamilton for 1991. Despite missing two early races, Green won the pole for the season-opening Goody's 300 and picked up a victory at Lanier Raceway, finishing thirteenth in points. He was runner-up to Jeff Gordon for Rookie of the Year honors. Green gave way to Jeff Burton for 1992. Burton achieved four top-five finishes, including a win at New Hampshire International Speedway, and finished ninth in points.
In 1993, Baby Ruth became the team's sponsor as FILMAR switched to Ford. Burton won at Myrtle Beach Speedway but the team dropped to fourteenth in points. That year also marked FILMAR's Winston Cup debut when Burton drove the No. 0 Ford at New Hampshire, starting sixth before a lap-three incident ended the race in 37th place.
After Burton left to pursue a Cup program with Stavola Brothers Racing, FILMAR hired Kenny Wallace for 1994. Wallace delivered the team's most productive Busch Series season, winning at Bristol, Martinsville, and Richmond and finishing fourth in points.
From 1995 onward, FILMAR split its effort between the Busch and Cup Series. In 1996, the team moved up to the Winston Cup full-time under Square D sponsorship with Wallace driving the No. 81 Ford. A seventh-place finish at North Carolina Speedway was a highlight; the team finished 28th in points. In 1997, Wallace claimed the team's first Cup poles, at Martinsville and Bristol, though only two top-ten finishes accompanied those results and the team dropped to 33rd in the standings.
Wallace's final full season with FILMAR in 1998 brought seven top-ten finishes, but the team failed to qualify for two races and finished 31st in points. At the end of the year, Wallace and sponsor Square D announced their departure to join Andy Petree Racing.
Martocci sold FILMAR to the Pinnacle Motorsports Group in 1999. The new owners planned to run the Daytona 500 with Morgan Shepherd but failed to qualify. Pinnacle subsequently sold the team again to Davis & Weight Motorsports later that season. Davis & Weight made their Busch debut at the Food City 250 and also fielded No. 55 and No. 81 entries in limited competition.
Michael Ritch drove for Davis & Weight in the 2000 Busch Series season, making 21 starts and recording five top-twenty finishes. Mark Green took over for 2001 and recorded a best finish of sixteenth at Darlington Raceway before the team announced it was abandoning its Busch program to concentrate on a Cup effort. After announcing plans to attempt the Brickyard 400, the team laid off all employees and did not compete again.
FILMAR's Busch Series operation served as a proving ground for several drivers who went on to significant Winston Cup careers. Bobby Hamilton, Jeff Burton, and David Green all drove for the team in its formative years. Jeff Burton in particular used his 1992 season with FILMAR — which included a Busch Series victory at New Hampshire — as a springboard to his Cup career with Stavola Brothers and later Roush Racing, where he became a race winner and championship contender.
