I own a 1996 fleetwood garland, and i am now in the process of repairing a soft floor,At present i have removed the carpet and have around 4 foot of floor to repair, I understand that you drill 1 inch holes every 6 inches or so on the floor you need to repair,As for the chemicals to use Can anyone recommend some and i understand appollo chemicals are good but i am unable to find any,Also when the job is done any ideas as to what i can fill the holes with?,would a car body filler do the job,and also is it worth boarding the floor all over when everything has hardened to give extra strength,And just as an after thought i didnt know weather to recarpet the van again or put a vinal flooring down,Any comments or suggestions please,Thanking you all in advance,
